Spring boot 项目遇到返回数据本应该是Json格式但是却返回了String类型的数据

整合springboot 项目遇到不少的问题，感觉有点吃力，发出来求助一下大神

1. 版本环境
   ide:Idea2018.1.2
   jdk:jdk1.8
   spring boot:1.5.2RELEASE
2. pom文件

3 . 本来应该是返回Json格式的数据但是返回的却是String 类型的数据

4 . 附上controller代码

package com.limit.controller;

import com.github.pagehelper.PageInfo;
import com.limit.Model.Persion;
import com.limit.service.PersionService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-0915:45
 */
//
//@Controller
@RestController
public class PersionController {

    @Autowired
    private PersionService persionService;

    @RequestMapping("getPersionList")

    public List getPersionList(){
       return persionService.getPersionList();
    }

    @RequestMapping("getPageInfo")
    //@ResponseBody
    public PageInfo getPageInfo(int pageNum,int pageSize){
        PageInfo pageInfo= persionService.listPage(1,10);
        return pageInfo;
    }
}

这样也不行

package com.limit.controller;

import com.github.pagehelper.PageInfo;
import com.limit.Model.Persion;
import com.limit.service.PersionService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-0915:45
 */
//
@Controller
//@RestController
public class PersionController {

    @Autowired
    private PersionService persionService;

    @RequestMapping("getPersionList")

    public List getPersionList(){
       return persionService.getPersionList();
    }

    @RequestMapping("getPageInfo")
    @ResponseBody
    public PageInfo getPageInfo(int pageNum,int pageSize){
        PageInfo pageInfo= persionService.listPage(1,10);
        return pageInfo;
    }
}

Model

package com.limit.Model;

import lombok.Data;
import lombok.Generated;

import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-0915:20
 */

@Table(name = "Persion")
@Data
public class Persion implements Serializable {

    private static final long serialVersionUID = 8157040516270067074L;
    @Id
    @GeneratedValue(generator = "JDBC")
    private String id;

    private String name;

    private String age;

    private String address;



}

5.在controller 从新键个类试下
Controller

package com.limit.controller;

import com.limit.Model.TestModel;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-1814:54
 */
@RestController
public class TestController {

    @RequestMapping("testJson")
    public TestModel testJson(){
        TestModel testModel = new TestModel();
        testModel.setNamge("张三");
        testModel.setAge("134");
        return testModel;
    }
}

Model

package com.limit.Model;

import lombok.Getter;
import lombok.Setter;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-1814:57
 */
public class TestModel {
    @Getter
    @Setter
    private String namge;

    @Getter
    @Setter
    private String age;

}

6.怀疑是用了lombok的问题

package com.limit.Model;

import lombok.Getter;
import lombok.Setter;

/**
 * @author fxl
 * @Title: ${file_name}
 * @Package ${package_name}
 * @Description: ${todo}
 * @date 2018-05-1814:57
 */
public class TestModel {

    private String namge;

    private String age;

    public String getNamge() {
        return namge;
    }

    public String getAge() {
        return age;
    }

    public void setNamge(String namge) {
        this.namge = namge;
    }

    public void setAge(String age) {
        this.age = age;
    }
}

问题还是没有解决，启动了别的项目发现没有这种问题，一直都在看什么有用就往项目里边整合什么，发现遇到一点问题都很难解决，所以决定系统化的学习一下springboot项目，网上找了一点资源，回头的笔记都记录在帖子里吧
