Junit4测试Controller

前言

使用注入controller的方式测试controller接口

Controller层

/*** 组织机构管理的处理*/
@Controller
@RequestMapping("/system/dept")
public class DeptController {/*** 组织机构管理服务*/@Autowiredprivate DeptService deptService;/*** 权限管理服务*/@Autowiredprivate AuthorService authorService;/*** 组织机构管理页面入口* @return 跳转到组织机构管理页面*/@RequestMapping("/show")public String show(ModelMap map, String menuId, HttpServletRequest request) {//得到用户信息UserInfo users = Util.getSessionUserInfo(request);//保存当前用户的所属区域map.put("regionCode", users.getRegionCode());//得到操作权限Map operation = authorService.getOperPermission(users.getRoleIdList(), menuId);map.put("operation", operation);return "system/organization/organizationList";}
}

测试结果

返回值：system/organization/organizationList

参考资料

• Spring自带mock测试Controller

结语

使用mockmvc测试controller时，显示authorService为null,即service注入失败，不知道是什么原因引起的，待解决。
