设置测试端口（见SpringBoot启用web模拟测试（一））

模拟测试启动（见SpringBoot启用web模拟测试（一））

测试模拟匹配（各组成信息皆可配置）

    resultActions.andExpect(json);

    ContentResultMatchers content1 = MockMvcResultMatchers.content();
    ResultMatcher json1 = content1.contentType("application/json");
    resultActions.andExpect(json1);

    //预计本次调用时成功的状态200
    ResultMatcher string = content2.string("{\"flag\":true,\"data\":{\"id\":null,\"type\":null,\"name\":\"333333\",\"description\":null},\"mess\":null}");
    //添加预计值到本次调用中进行匹配
    resultActions.andExpect(string);
