一些实体类

CheckedParam

用于包装页面传进来的参数

package com.proc.model;
import java.util.List;
public class CheckedParam {
	//业务标记,由页面传入,用于审批时页面根据tagPageJs解析data,渲染到页面,审批管理员可看到审批的内容
	private String tagPageJs;
	//页面传入的原始数据
	private List<String> data;
	public String getTagPageJs() {
		return tagPageJs;
	}
	public void setTagPageJs(String tagPageJs) {
		this.tagPageJs = tagPageJs;
	}
	public List<String> getData() {
		return data;
	}
	public void setData(List<String> data) {
		this.data = data;
	}

}

				+ ", description=" + description + ", paramTypes=" + paramTypes + ", paramArgs=" + paramArgs + ", data="
				+ data + "]";
	}

}

	}

	public static <T> String toCanonical (TypeReference<T> tr) {
		return MAPPER.getTypeFactory().constructType(tr).toCanonical();
	}

	//反序列化时从持久数据中获取JavaType
	public static JavaType constructFromCanonical (String canonical) {

	public static String[] toStrings (Object[] objs) {
		List<String> list = new ArrayList<>();
		try {
			for (Object obj : objs) {
				list.add(MAPPER.writeValueAsString(obj));
			}
		} catch (Exception e) {
			throw new RuntimeException("序列化对象出错", e);
		}
		return list.toArray(new String[0]);
	}

	public static String encode (String[] strs) {
		List<String> list = new ArrayList<>();
		for (String str : strs) {
			list.add(Base64.getEncoder().encodeToString(str.getBytes(StandardCharsets.UTF_8)));

		return join;
	}

	public static String[] decode (String text) {
		String[] strs = text.split("\\|", -1);
		List<String> list = new ArrayList<>();
		for (String base64 : strs) {

		}
		return list.toArray(new String[0]);
	}

	public static String encodeZip (Object[] objs) {
		return encodeZip(toStrings(objs));
	}

	public static String encodeZip (String[] strs) {
		List<String> list = new ArrayList<>();
		for (String str : strs) {
			list.add(StringZipUtil.zipBase64(str));
		}
		String join = list.stream().collect(Collectors.joining("|"));
		return StringZipUtil.zipBase64(join);
	}

	public static String[] decodeZip (String text) {
		String str = StringZipUtil.unzipBase64(text);
		String[] strs = str.split("\\|", -1);
		List<String> list = new ArrayList<>();
		for (String base64 : strs) {
			list.add(StringZipUtil.unzipBase64(base64));
		}
		return list.toArray(new String[0]);
	}
}

SpringBootBeanUtil

package com.proc.util;
import java.util.Map;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
@Component
public class SpringBootBeanUtil implements ApplicationContextAware {

	private static ApplicationContext applicationContext;
	@Override
	public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
		SpringBootBeanUtil.applicationContext = applicationContext;
	}

	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}
	public static Object getBean(String name) {
		return applicationContext.getBean(name);
	}

	public static <T> T getBean(Class<T> clazz) {
		return (T) applicationContext.getBean(clazz);
	}

	public static <T> T getBean(String name, Class<T> clazz) {
		return applicationContext.getBean(name, clazz);
	}

	public static <T> Map<String, T> getBeansOfType(Class<T> clazz) {
		return applicationContext.getBeansOfType(clazz);
	}

}

ProcessBeanUtil

用于执行目标方法

package com.proc.util;
import java.lang.reflect.Method;
import org.springframework.util.ReflectionUtils;
public class ProcessBeanUtil {
	private ProcessBeanUtil () {}

	public static Object excuteBeanMethod (String targetClassName, String methodName, Class<?>[] parameterTypes, Object[] args) {
		Class<?> targetClass;
		try {
			targetClass = Class.forName(targetClassName);
		} catch (ClassNotFoundException e) {
			throw new RuntimeException("未找到类", e);
		}
		return excuteBeanMethod(targetClass, methodName, parameterTypes, args);
	}

	public static Object excuteBeanMethod (Class<?> targetClass, String methodName, Class<?>[] parameterTypes, Object[] args) {
		Object bean = SpringBootBeanUtil.getBean(targetClass);
		Method method = ReflectionUtils.findMethod(targetClass, methodName, parameterTypes);
		return ReflectionUtils.invokeMethod(method, bean, args);
	}
}

CheckedTransmitableUtil

用于传递业务参数

package com.proc.util;
import com.alibaba.ttl.TransmittableThreadLocal;
import com.proc.model.CheckedParam;
public class CheckedTransmitableUtil {
	private static final TransmittableThreadLocal<CheckedParam> threadLocal = new TransmittableThreadLocal<>();

	private CheckedTransmitableUtil () {}

	}

	public static CheckedParam getAndRemove () {
		CheckedParam checkedParam = threadLocal.get();
		threadLocal.remove();
		return checkedParam;
	}
}

PrivateTransmitableUtil

为Aspect判断是否拦截提供依据

package com.proc.util;
import com.alibaba.ttl.TransmittableThreadLocal;
public class PrivateTransmitableUtil {

	private static final String CHECKED = "__CHECKED__";
	private static final TransmittableThreadLocal<String> threadLocal = new TransmittableThreadLocal<>();

	private PrivateTransmitableUtil () {}

	public static void set () {
		threadLocal.set(CHECKED);
	}

	//是否执行的审批程序
	public static boolean isCheck () {
		String checked = threadLocal.get();
		threadLocal.remove();
		return CHECKED.equals(checked);
	}
}

一些Bean

PostProcess

用于拦截方法后做的个性处理

package com.proc.bean;
public interface PostProcess<T> {
	//返回说明内容,审批时在页面显示
	String description(String tag, Class<?>[] parameterTypes, Object[] args);

	//返回代替的返回值
	T retObject(String tag, Class<?>[] parameterTypes, Object[] args);
}

TestCheckPostProcess

测试用

package com.proc.bean;
import org.springframework.stereotype.Component;
@Component
public class TestCheckPostProcess implements PostProcess<String> {
	@Override
	public String description(String tag, Class<?>[] parameterTypes, Object[] args) {
		return tag + "测试testCheck";
	}
	@Override
	public String retObject(String tag, Class<?>[] parameterTypes, Object[] args) {
		return tag + "返回拦截响应";
	}
}

Aspect注解

package com.proc.config;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import com.proc.bean.PostProcess;
@Retention(RUNTIME)
@Target(METHOD)
public @interface Checked {

	String tag() default "";
	/**
	 * @see com.proc.util.JacksonCanonicalUtil
	 * @return
	 */
	String[] paramCanonical();

	Class<? extends PostProcess<?>> postProcess();
}

切面类 CheckedAop

package com.proc.config;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.proc.bean.PostProcess;
import com.proc.model.CheckedParam;
import com.proc.model.ProcessDbModel;
import com.proc.service.ProcessDbService;
import com.proc.util.Base64Util;
import com.proc.util.CheckedTransmitableUtil;
import com.proc.util.PrivateTransmitableUtil;
import com.proc.util.SpringBootBeanUtil;
@Component
@Aspect
public class CheckedAop {

	@Autowired
	private ProcessDbService processDbService;
	//拦截Checked注释的方法
	@Pointcut("@annotation(com.proc.config.Checked)")
	public void check() {
	}

	@Around(value = "com.proc.config.CheckedAop.check() && @annotation(checked)")
	public Object around(ProceedingJoinPoint joinPoint, Checked checked) throws Throwable {
		MethodSignature signature = (MethodSignature) joinPoint.getSignature();
		Class<?>[] parameterTypes = signature.getParameterTypes();
		String methodName = signature.getMethod().getName();
		Object[] args = joinPoint.getArgs();
		if (PrivateTransmitableUtil.isCheck()) {
			//审批后,执行业务代码
			Object returnVal = joinPoint.proceed();
			return returnVal;
		} else {
			//不是审批操作,拦截
			Class<? extends PostProcess<?>> postProcess = checked.postProcess();
			PostProcess<?> bean = SpringBootBeanUtil.getBean(postProcess);
			//组装持久化数据
			ProcessDbModel dbModel = new ProcessDbModel();
			dbModel.setTargetClassName(joinPoint.getTarget().getClass().getName());
			dbModel.setMethodName(methodName);
			String tag = checked.tag();
			CheckedParam checkedParam = CheckedTransmitableUtil.getAndRemove();
			if (checkedParam == null || checkedParam.getTagPageJs() == null || checkedParam.getTagPageJs().isEmpty()) {
				//不是页面调用的业务,使用注解的tag,data保存为service的参数,这时需要页面专门解析渲染
				String[] argStrs = Base64Util.toStrings(args);
				dbModel.setParamArgs(Base64Util.encodeZip(argStrs));
				dbModel.setData(Base64Util.encode(argStrs));
			} else {
				tag = checkedParam.getTagPageJs();
				dbModel.setParamArgs(Base64Util.encodeZip(args));
				dbModel.setData(Base64Util.encode(checkedParam.getData().toArray(new String[0])));
			}
			dbModel.setTag(tag);
			dbModel.setParamTypes(Base64Util.encodeZip(checked.paramCanonical()));
			dbModel.setDescription(bean.description(tag, parameterTypes, args));
			//持久化数据
			processDbService.save(dbModel);
			return bean.retObject(tag, parameterTypes, args);
		}
	}
}

线程池配置

测试用

package com.proc.config;
import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import com.alibaba.ttl.threadpool.TtlExecutors;
@Configuration
public class TaskExecutePoolConfig {
	@Bean
	public Executor processExecutor() {
		ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
		//核心线程池大小
		executor.setCorePoolSize(10);
		//最大线程数
		executor.setMaxPoolSize(10);
		//队列容量
		executor.setQueueCapacity(500);
		//活跃时间
		executor.setKeepAliveSeconds(60);
        //线程名字前缀
		executor.setThreadNamePrefix("ProcessExecutor-");

		executor.setRejectedExecutionHandler(new ThreadPoolExecutor.AbortPolicy());
		// 等待所有任务结束后再关闭线程池
		executor.setWaitForTasksToCompleteOnShutdown(true);
		executor.initialize();
		//用transmittable-thread-local包装,才可以正确给线程池中的线程传递数据
		return TtlExecutors.getTtlExecutor(executor);
	}
}

持久化service

为测试方便,未真正实现持久化

package com.proc.service;

import com.proc.model.ProcessDbModel;

public interface ProcessDbService {

	void save (ProcessDbModel model);

	ProcessDbModel get ();
}
package com.proc.service.impl;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import com.proc.model.ProcessDbModel;
import com.proc.service.ProcessDbService;

@Component
public class ProcessDbServiceImpl implements ProcessDbService {
	private static final Logger log = LoggerFactory.getLogger(ProcessDbService.class);

	private volatile ProcessDbModel model;

	@Override
	public void save(ProcessDbModel model) {
		this.model = model;
		log.info(model.toString());
	}

	@Override
	public ProcessDbModel get() {
		return this.model;
	}

}

审批用的service

	private static final JsonMapper MAPPER = new JsonMapper();
	@Override
	public void process(ProcessDbModel model) {
		PrivateTransmitableUtil.set();
		String[] paramArgs = Base64Util.decodeZip(model.getParamArgs());
		String[] paramTypes = Base64Util.decodeZip(model.getParamTypes());
		List<Class<?>> parameterTypes = new ArrayList<>();
		List<Object> args = new ArrayList<>();
		try {
			for (int i = 0; i < paramTypes.length; i++) {
				JavaType javaType = JacksonCanonicalUtil.constructFromCanonical(paramTypes[i]);
				parameterTypes.add(javaType.getRawClass());
				args.add(MAPPER.readValue(paramArgs[i], javaType));
			}
		} catch (JsonProcessingException e) {
			throw new RuntimeException("反序列化对象出错", e);
		}

		Object ret = ProcessBeanUtil.excuteBeanMethod(

				model.getMethodName(),
				parameterTypes.toArray(new Class<?>[0]),
				args.toArray(new Object[0])
				);
		log.info(Objects.toString(ret));
	}
}

测试用的service

import com.proc.model.Person;
import com.proc.model.Score;
public interface TestService {
	String testCheck(Person<Score> person, String team);

	String testCheck2(Person<Score> person, String team);

	@Override
	public String testCheckAsync(Person<Score> person, String team) {
		log.info(team + ">>>>" + person);
		return "target方法";
	}
}

测试用的controller

package com.proc.ctrl;
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import com.proc.model.CheckedParam;
import com.proc.model.Person;
import com.proc.model.Score;
import com.proc.service.TestService;
import com.proc.util.CheckedTransmitableUtil;
@RestController
public class TestController {
	@Autowired
	private TestService testService;

	//模拟页面调用
	@GetMapping(value = "index")
	public String testCheck() {
		CheckedParam checkedParam = new CheckedParam();
		checkedParam.setTagPageJs("01");
		List<String> data = new ArrayList<>();
		data.add("前端传进来的数据1");
		data.add("前端传进来的数据2");
		checkedParam.setData(data);
		CheckedTransmitableUtil.set(checkedParam);
		Person<Score> person = new Person<>();
		person.setName("一个人");
		person.setAge("18");
		person.setSex("1");
		person.setSalary("20000.00");
		person.setTestName("测试人");
		person.setWork("工作");

		Score score1 = new Score();
		score1.setEnglish(new BigDecimal("12.4"));
		score1.setLangue(new BigDecimal("764"));
		score1.setMath(new BigDecimal("87.4"));
		Score score2 = new Score();
		score2.setEnglish(new BigDecimal("12.4"));
		score2.setLangue(new BigDecimal("764"));
		score2.setMath(new BigDecimal("87.4"));
		List<Score> list = new ArrayList<>();
		list.add(score1);
		list.add(score2);
		person.setGrades(list);

		testService.testCheck(person, "team>>>>>>>>");
		return "12345";
	}

	//模拟其他渠道调用
	@GetMapping(value = "index2")
	public String testCheck2() {
		Person<Score> person = new Person<>();
		person.setName("一个人");
		person.setAge("18");
		person.setSex("1");
		person.setSalary("20000.00");
		person.setTestName("测试人");
		person.setWork("工作");

		Score score1 = new Score();
		score1.setEnglish(new BigDecimal("12.4"));
		score1.setLangue(new BigDecimal("764"));
		score1.setMath(new BigDecimal("87.4"));
		Score score2 = new Score();
		score2.setEnglish(new BigDecimal("12.4"));
		score2.setLangue(new BigDecimal("764"));
		score2.setMath(new BigDecimal("87.4"));
		List<Score> list = new ArrayList<>();
		list.add(score1);
		list.add(score2);
		person.setGrades(list);

		testService.testCheck2(person, "team>>>2>>>>>");
		return "12345";
	}

	//模拟调用异步方法
	@GetMapping(value = "index3")
	public String testCheckAsync() {
		CheckedParam checkedParam = new CheckedParam();
		checkedParam.setTagPageJs("01");
		List<String> data = new ArrayList<>();
		data.add("前端传进来的数据1");
		data.add("前端传进来的数据2");
		checkedParam.setData(data);
		CheckedTransmitableUtil.set(checkedParam);
		Person<Score> person = new Person<>();
		person.setName("一个人");
		person.setAge("18");
		person.setSex("1");
		person.setSalary("20000.00");
		person.setTestName("测试人");
		person.setWork("工作");

		Score score1 = new Score();
		score1.setEnglish(new BigDecimal("12.4"));
		score1.setLangue(new BigDecimal("764"));
		score1.setMath(new BigDecimal("87.4"));
		Score score2 = new Score();
		score2.setEnglish(new BigDecimal("12.4"));
		score2.setLangue(new BigDecimal("764"));
		score2.setMath(new BigDecimal("87.4"));
		List<Score> list = new ArrayList<>();
		list.add(score1);
		list.add(score2);
		person.setGrades(list);

		testService.testCheckAsync(person, "team>>>3>>>>>");
		return "12345";
	}
}

开启异步功能

package com.proc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;
@SpringBootApplication
@EnableAsync
public class ProcessTestApplication {
	public static void main(String[] args) {
		SpringApplication.run(ProcessTestApplication.class, args);
	}
}

测试

http://localhost:8080/indexhttp://localhost:8080/index2http://localhost:8080/index3
浏览器访问上面其中一个路径一次,再访问http://localhost:8080/process一次即可
