现在,当使用 json 发送请求时,不会调用控制器方法。如果我删除方法参数“@RequestBody DateRequest systemDate”,该方法将被调用,控制台显示语句。

使用的控制器是@RestController

//headers={"Accept=application/json", "Content-Type=application/json"}
    @RequestMapping(value="/retrieveStartandEndDates",method=RequestMethod.POST,consumes={"application/json"} , headers={"Accept=application/json", "Content-Type=application/json"})
    public RetrieveStartEndDates retrieveStartandEndDates(@RequestBody DateRequest systemDate){
        //RetrieveStartEndDates systemDate = new RetrieveStartEndDates();
        System.out.println("inside controller:::"+systemDate.getSystemDate());
        RetrieveStartEndDates obj = new RetrieveStartEndDates();
        obj = schemeService.getStartAndEndDates(systemDate.getSystemDate());
        System.out.println(obj.toString());
        return obj;
    }

DateRequest 是一个简单的 DTO 对象

package com.demo.vo;

public class DateRequest {

    private String SystemDate;
    private String dest;
    public String getSystemDate() {
        return SystemDate;
    }
    public void setSystemDate(String systemDate) {
        this.SystemDate = systemDate;
    }
    public String getDest() {
        return dest;
    }
    public void setDest(String dest) {
        this.dest = dest;
    }

}

JSON 请求

{SystemDate:“12/23/2016”,dest:“retrieveStartandEndDates”}

不知道我在这里错过了什么。任何建议/帮助表示赞赏。

尝试使用org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter而不是org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter在 dispatcher-servlet.xml 中。
