该博客展示了如何使用SpringMVC的@Controller和@RequestMapping注解处理POST请求，通过@RequestBody从JSON字符串中接收List<Greeting>对象，并通过@ResponseBody以JSON格式返回。Greeting类包含id和content属性，确保了数据的序列化和反序列化。

    $(document).ready(function(){
        var saveDataAry=[];
        var data1={"id":1,"content":"gz"};
        var data2={"id":2,"content":"gr"};
        saveDataAry.push(data1);
        saveDataAry.push(data2);
        $.ajax({
            type:"POST",
            url:"ajax/saveUser",
            dataType:"json",
            contentType:"application/json",
            data:JSON.stringify(saveDataAry),
            success:function(data){
                $.each(data, function( k, v ) {
                   alert("int:" +k+"---"+"id: " + v.id + ", content: " + v.content );
               });
            }
         });
    });

后台

@Controller
@RequestMapping("/ajax")
public class AjaxJsonController {

    @RequestMapping(value = "/saveUser", method = {RequestMethod.POST })
    @ResponseBody
    public List<Greeting> saveUser(@RequestBody List<Greeting> greeting) {
          return greeting;
    }
}

pojo

public class Greeting{
private long id;
private String content;

    //添加无参的构造器
    public Greeting(){
    }

    public Greeting(long id, String content) {
        this.id = id;
        this.content = content;
    }

   public void setId(long id) {
       this.id = id;
   }

    public void setContent(String content) {
       this.content = content;
   }
   public long getId() {
        return id;
    }
    public String getContent() {
        return content;
    }
