Spring MVC 数据绑定-对象数组

Model:

public class TestInfo implements Serializable {

    private String id;
    private String name;

    public TestInfo() {
    }

    public TestInfo(String id, String name) {
        this.id = id;
        this.name = name;
    }

    public String getId() {
        return this.id;
    }

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

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Controller:

@RequestMapping(value = "/t5",method = RequestMethod.POST)
@ResponseBody
public void createListTestInfos(HttpServletRequest request, HttpServletResponse response,
                                    @RequestBody List<TestInfo> testInfos) {
    System.out.println(testInfos.size());
}

Ajax:

$("#testInfo4").click(function () {
    var tetsInfo2 = {
        id:"123",
        name:"fang",
    };
    var tetsInfo21 = {
        id:"456",
        name:"fan",
    };
    var testInfos = [];
    testInfos.push(tetsInfo2);
    testInfos.push(tetsInfo21);
    $.ajax({
        url:'http://127.0.0.1:8089/server/tarry/t5',
        type:'post',
        contentType: "application/json",
        data:JSON.stringify(testInfos),
        dataType:'json',
        success:function(data){
            console.log(data);
        }

    });
});
