先在pom.xml添加 json 库

<dependency>  
<groupId>com.alibaba</groupId>  
<artifactId>fastjson</artifactId>  
<version>1.2.35</version>  
</dependency>

controller :

package com.example.demo.controller;
    
    import com.example.demo.RequestCon;
    import com.example.demo.ReturnBody;
    
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class HomeController {
    
        @RequestMapping("/test")
        public String Index() {
    
            return "1111";
        }
    
        @RequestMapping("/test2")
        public ReturnBody test2(@RequestBody RequestCon req) {
    
            ReturnBody rb = new ReturnBody();
    
            try {
                rb.code = "server 0";
                rb.setMsg(req.msg + "  server");
    
            } catch (Exception ex) {
    
                rb.setCode("0");
                rb.setMsg("ex " + ex.getMessage());
    
            }
            return rb;
        }
    
    }

RequestCon:

package com.example.demo;
    
    public class RequestCon {
    
        public String code;
        public String msg;
    
    
    /**
     * @param code the code to set
     */
    public void setCode(String code) {
        this.code = code;
    }
    /**
     * @return the code
     */
    public String getCode() {
        return code;
    }
    /**
     * @param msg the msg to set
     */
    public void setMsg(String msg) {
        this.msg = msg;
    }
    /**
     * @return the msg
     */
    public String getMsg() {
        return msg;
    }
    
    }

ReturnBody:

package com.example.demo;
    
    public class ReturnBody {
    
        public String code;
        public String msg;
    
    
    /**
     * @param code the code to set
     */
    public void setCode(String code) {
        this.code = code;
    }
    /**
     * @return the code
     */
    public String getCode() {
        return code;
    }
    /**
     * @param msg the msg to set
     */
    public void setMsg(String msg) {
        this.msg = msg;
    }
    /**
     * @return the msg
     */
    public String getMsg() {
        return msg;
    }    
    
    
    }
