3、swapper配置

package main.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class SwaggerConfig {
 @Bean
 public Docket createRestApi() {
  return new Docket(DocumentationType.SWAGGER_2)
    .apiInfo(apiInfo())
    .select()
    .apis(RequestHandlerSelectors.basePackage("main.controller"))
    .paths(PathSelectors.any())
    .build();

 }

 //配置在线文档的基本信息
 private ApiInfo apiInfo() {
  return new ApiInfoBuilder()
    .title("springboot利用swagger构建api文档")
    .description("简单优雅的restfun风格，https://me.csdn.net/blog/miachen520")
    .termsOfServiceUrl("https://me.csdn.net/blog/miachen520")
    .version("1.0")
    .build();

 }
}

4、跨域配置

package main.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class webConfig implements WebMvcConfigurer {

 @Override
 public void addCorsMappings(CorsRegistry registry) {
  // 设置允许跨域的路径
  registry.addMapping("/**")
    // 设置允许跨域请求的域名
    .allowedOrigins("*")
    // 是否允许证书
    .allowCredentials(true)
    .allowedMethods("*")
    .maxAge(3600);
 }
}

5、Redis序列化

serializer:

package main.config;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.parser.ParserConfig;
import com.alibaba.fastjson.serializer.SerializerFeature;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.SerializationException;
import java.nio.charset.Charset;
public class FastJsonRedisSerializer<T> implements RedisSerializer<T> {
 public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");
 private Class<T> clazz;
 public FastJsonRedisSerializer(Class<T> clazz) {

  super();

  this.clazz = clazz;

 }

 @Override
 public byte[] serialize(T t) throws SerializationException {

  if (null == t) {

   return new byte[0];

  }

  return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);

 }

 @Override
 public T deserialize(byte[] bytes) throws SerializationException {

  if (null == bytes || bytes.length <= 0) {

   return null;

  }

  String str = new String(bytes, DEFAULT_CHARSET);
  ParserConfig.getGlobalInstance().setAutoTypeSupport(true);
  return (T) JSON.parseObject(str, clazz);
 }
}

config:

package main.config;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.data.redis.RedisProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration

@ConditionalOnClass(RedisOperations.class)

@EnableConfigurationProperties(RedisProperties.class)

public class redisConfig {
 @Bean

 @ConditionalOnMissingBean(name = "redisTemplate")

 public RedisTemplate<Object, Object> redisTemplate(

   RedisConnectionFactory redisConnectionFactory) {

  RedisTemplate<Object, Object> template = new RedisTemplate<>();

  //使用fastjson序列化

  FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);

  // value值的序列化采用fastJsonRedisSerializer

  template.setValueSerializer(fastJsonRedisSerializer);

  template.setHashValueSerializer(fastJsonRedisSerializer);

  // key的序列化采用StringRedisSerializer

  template.setKeySerializer(new StringRedisSerializer());

  template.setHashKeySerializer(new StringRedisSerializer());

  template.setConnectionFactory(redisConnectionFactory);

  return template;

 }

 @Bean
 @ConditionalOnMissingBean(StringRedisTemplate.class)

 public StringRedisTemplate stringRedisTemplate(

   RedisConnectionFactory redisConnectionFactory) {

  StringRedisTemplate template = new StringRedisTemplate();

  template.setConnectionFactory(redisConnectionFactory);

  return template;

 }
}
