package com.test.controller; import com.test.bean.Result; import com.test.entity.Menu; import com.test.services.TestService; import io.swagger.annotations.Api; import io.swagger.annotations.ApiOperation; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; import java.util.List; /** * 测试 */ @RestController @RequestMapping("/test") @Api(tags = "测试") public class TestController { @Autowired private TestService testService; @RequestMapping(value = "getMenu", method = RequestMethod.GET) @ApiOperation(value = "获取菜单信息-关联方式") public Result getMenu() { List<Menu> menus = testService.selectMenu(); Result result = new Result(); result.setData(menus); result.setSuccess(true); return result; } @RequestMapping(value = "getNestedMenu", method = RequestMethod.GET) @ApiOperation(value = "获取菜单信息-嵌套方式") public Result getNestedMenu() { List<Menu> menus = testService.selectNestedMenu(); Result result = new Result(); result.setData(menus); result.setSuccess(true); return result; } }
