springboot 跨域配置类及跨域请求配置

下面通过代码看下springboot 跨域配置类，代码如下所示：

ackage org.fh.config;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Component;
/**

 */
@Component
public class CORSFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        HttpServletRequest request = (HttpServletRequest) servletRequest;
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        response.setContentType("textml;charset=UTF-8");
        response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "0");
        response.setHeader("Access-Control-Allow-Headers","Origin, No-Cache, X-Requested-With, If-Modified-Since, Pragma, Last-Modified, Cache-Control, Expires, Content-Type, X-E4M-With,userId,token");
        response.setHeader("Access-Control-Allow-Credentials", "true"); // 是否支持cookie跨域
        response.setHeader("XDomainRequestAllowed", "1");
        filterChain.doFilter(servletRequest, servletResponse);
    }
    @Override
    public void destroy() {
    }
}

1.模型管理：web在线流程设计器、导入导出xml、复制流程、部署流程

2.流程管理：导入导出流程资源文件、查看流程图、根据流程实例反射出流程模型、激活挂起

3.运行中流程：查看流程信息、当前任务节点、当前流程图、作废暂停流程、指派待办人、自由跳转

4.历史的流程：查看流程信息、流程用时、流程状态、查看任务发起人信息

5.待办任务：查看本人个人任务以及本角色下的任务、办理、驳回、作废、指派一下代理人

6.已办任务：查看自己办理过的任务以及流程信息、流程图、流程状态(作废 驳回 正常完成)

补充：下面看下springboot跨域请求配置的两种方法

方式一：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
public class CorsConfig {
    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*"); // 允许任何域名使用
        corsConfiguration.addAllowedHeader("*"); // 允许任何头
        corsConfiguration.addAllowedMethod("*"); // 允许任何方法（post、get等）
        corsConfiguration.setAllowCredentials(true);
        return corsConfiguration;
    }
    
    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig()); // 对接口配置跨域设置
        return new CorsFilter(source);
    }
}

方式二：

import org.springframework.context.annotation.Configuration;
import org.springframework.core.Ordered;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration //加配置注解可以扫描到
public class WebConfig implements WebMvcConfigurer{
    
    //跨域请求配置
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        WebMvcConfigurer.super.addCorsMappings(registry);
        registry.addMapping("/**")// 对接口配置跨域设置
                .allowedHeaders("*")// 允许任何头
                .allowedMethods("POST","GET")// 允许方法（post、get等）
                .allowedOrigins("*")// 允许任何域名使用
                .allowCredentials(true);
    }
    
}
