  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
• Controller 层

• 　　View 层
• 　　 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
          }
     });
  

  OR

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

• 获取ID为1 的用户

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

  • 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
       }
    });

  • 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
       }
    });
