【SpringBoot】SpringBoot 构建RestFul API 含单元测试

首先，回顾并详细说明一下在快速入门中使用的 @Controller 、 @RestController 、 @RequestMapping 注解。如果您对Spring MVC不熟悉并且还没有尝试过快速入门案例，建议先看一下快速入门的内容。

@Controller ：修饰class，用来创建处理http请求的对象
@RestController ：Spring4之后加入的注解，原来在 @Controller 中返回json需要 @ResponseBody 来配合，如果直接用 @RestController 替代 @Controller 就不需要再配置 @ResponseBody ，默认返回json格式。
@RequestMapping ：配置url映射

一、Controller 层

package com.creditease.bsettle.crm.controller.user;

import com.creditease.bsettle.crm.model.User;
import com.creditease.bsettle.crm.service.UserService;
import com.creditease.bsettle.crm.util.ResponseUtil;
import com.creditease.bsettle.monitor.base.controller.BaseCommonQueryController;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.Map;

@Slf4j
@RequestMapping(value = "/v1/users")
@RestController
public class UserControllerRestFulDemo extends BaseCommonQueryController{

    @Autowired
    UserService userService;

    @RequestMapping(value = "",method = RequestMethod.GET)
    @ResponseBody
    public Map pageList(HttpServletRequest request, @RequestParam Map searchParams) {
        Map maps = new HashMap();
        try {
            //TODO do something
            //maps = userService.queryPage(searchParams);
        } catch (Exception var4) {
            log.error(var4.getMessage(), var4);
            maps.put("retCode", Boolean.valueOf(false));
            maps.put("retMessage", var4.getMessage());
        }

        return maps;
    }

    /**
     * 根据用户ID 查询用户信息
     * @param request
     * @param id
     * @return
     */
    @RequestMapping(value = "/{id}",method = RequestMethod.GET)
    @ResponseBody
    Map  findUser(HttpServletRequest request,@PathVariable Long id) {
        Map resultMap = ResponseUtil.createMap(true,"操作成功！");
        try {
            //TODO do something
           /* User user = userService.findUserById(id);
            resultMap.put("user",user);*/
        }catch(Exception e){
            log.error("findUserById is Exception !!! {} \n",e);
            resultMap = ResponseUtil.createMap(false,"操作失败！"+e.getMessage());
        }
        return resultMap;
    }

    /**
     * 修改用户信息
     * @param request
     * @param user
     * @param updateType 修改类型  1：修改密码  2：修改用户信息  3：修改用户状态
     * @return
     */
    @RequestMapping(value="/{id}", method = RequestMethod.PUT)
    @ResponseBody
    Map updateUserInfo(HttpServletRequest request,@ModelAttribute User user,@PathVariable Long id,
                                      @RequestParam("updateType") int updateType){
        Map resultMap = ResponseUtil.createMap(true,"操作成功！");
        try{
            //TODO do something
           // userService.updateUser(user,updateType,id);
        }catch (Exception e){
            log.error("updateUserInfo is Exception !!! {} \n",e);
            resultMap = ResponseUtil.createMap(false,"操作失败！"+e.getMessage());
        }
        return resultMap;
    }

    /**
     * 根据用户ID删除用户
     * @param request
     * @param id
     * @return
     */
    @RequestMapping(value="/{id}", method = RequestMethod.DELETE)
    @ResponseBody
    Map delUserById(HttpServletRequest request,@PathVariable Long id){
        Map resultMap = ResponseUtil.createMap(true,"操作成功！");
        try{
            //TODO do something
            //userService.delete(id);
        }catch (Exception e){
            log.error("delUserById is Exception !!! {} \n",e);
            resultMap = ResponseUtil.createMap(false,"操作失败！"+e.getMessage());
        }
        return resultMap;
    }
    /**
     * 保存用户信息
     * @param request
     * @param user
     * @return
     */
    @RequestMapping(value = "", method = RequestMethod.POST)
    @ResponseBody
    Map saveUserInfo(HttpServletRequest request, @ModelAttribute User user){
        Map resultMap = ResponseUtil.createMap(true,"操作成功！");
        try{
            //TODO do something
           //userService.save(user);
        }catch (Exception e){
            log.error("saveUserInfo is Exception !!! {} \n",e);
            resultMap = ResponseUtil.createMap(false,"操作失败！"+e.getMessage());
        }
        return resultMap;
    }
}

二、View 层 1. 根据查询条件获取user列表

$.ajax({
       url: '../v1/users',
       async: false,
       type: 'GET',
       dataType: 'json
       data: {
           //TODO
       } ,
       success: function(data) {        
                  //TODO  
        }
   });

$('#userTable').bootstrapTable({
    method: 'GET',
    url: '../v1/user',
    dataType: 'json',
    pagination: true,
    pageList: [5,10,15,20],
    pageNumber: 1,
    pageSize: 5,
    //singleSelect: true,
    clickToSelect: true,
    sidePagination: 'server',
    queryParams: queryParams,
    locale: 'zh-CN',
    //  略
})

2. 获取ID为1 的用户

$.ajax({
   url: '../v1/user/1',
   type: 'GET',
   dataType: 'json',
   data: {
        //TODO
   },
   success: function(data) {
      //TODO
   }
});

3. 更新用户ID为1 的用户信息

$.ajax({
   url: '../v1/user/1',
   type: 'PUT',
   dataType: 'json',
   data: {
      //TODO new user data
   },
   success: function(data) {
      //TODO
   }
});

4. 删除用户ID为1的用户

$.ajax({
   url: '../v1/user/1',
   type: 'DELETE',
   dataType: 'json',
   data: {
      //TODO other param
   },
   success: function(data) {
     //TODO
   }
});

三、测试用例

                .andExpect(content().contentType("application/json;charset=UTF-8"));
    }

    @Test
    public void postUser() throws Exception {
        // 2、post提交一个userRequestBuilder

                .param("isModifyPassword","N")

        mvc.perform(request)
                .andDo(print());

    }

    @Test
    public void getUser() throws Exception {

                .header("auth","false")

                .param("pageSize", "10");;
        mvc.perform(request)
                .andDo(print())
                .andExpect(status().isOk());
    }

    @Test
    public void getUserById() throws Exception {
        // get一个id为1的user
        RequestBuilder  request = MockMvcRequestBuilders.get("/v1/user/1")
                .header("auth","false");
        mvc.perform(request)

    @Test
