项目名restfu-api-demo

基于 Spring Boot 2.1.6.RELEASE

介绍

RESTFUL是一种网络应用程序的设计风格和开发方式，基于HTTP，可以使用XML格式定义或JSON格式定义。RESTFUL适用于移动互联网厂商作为业务使能接口的场景，实现第三方OTT调用移动网络资源的功能，动作类型为新增、变更、删除所调用资源

2.分组校验

实体类定义如下：

public class User implements Serializable  {
    private static final long serialVersionUID = 1838417777538323571L;

    //主键
    @NotNull(message = "主键不能为空",groups =Update.class)
    private Long id;
    //用户名
    @NotNull(message = "用户名不能为空")
    private String userName;
    //密码
    @NotNull(message = "密码不能为空")
    private String password;
    //性别
    @NotNull(message = "性别不能为空")
    private String sex;


    public @interface Update {
    }
}

控制层代码,BindingResult bindingResult 必须写在方法的接收参数上，否则校验失败，校验逻辑统一走@FwValidate切面处理

/**
     * 添加用户
     * @Author xuyisu
     * @Date 2019/10/25
     * @Param [user]
     * @Return com.yisu.common.result.FwResult
     */
    @PostMapping
    @ApiOperation(value = "创建用户")
    @FwValidate
    public FwResult createUser(@Valid @RequestBody User user,BindingResult bindingResult) {
        if(bindingResult.hasErrors())
        {
            return FwResult.failed();
        }
        FwResult userInfo=userService.createUser(user);
        return userInfo;
    }

    /**
     * 更新用户
     * @Author xuyisu
     * @Date 2019/10/25
     * @Param [user]
     * @Return com.yisu.common.result.FwResult
     */
    @PutMapping("/updateUser")
    @ApiOperation(value = "更新用户")
    @FwValidate
    public FwResult updateUser(@Validated(User.Update.class) @RequestBody User user,BindingResult bindingResult) {
        if(bindingResult.hasErrors())
        {
            return FwResult.failed();
        }
        FwResult userInfo=userService.updateUser(user);
        return userInfo;
    }

3.swagger 配置

/**
 * api页面 /swagger-ui.html
 * @author xuyisu
 * @date 2019-10-15
 */

@Configuration
@EnableSwagger2
public class SwaggerConfig {


    @Value("${swagger.enabled}")
    private Boolean enabled;

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(enabled)
                .apiInfo(apiInfo())
                .select()
                .paths(Predicates.not(PathSelectors.regex("/error.*")))
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口文档")
                .version("1.0")
                .build();
    }

}

浏览器输入http://localhost:8766/swagger-ui.html#

4.单元测试

/**
 * @ClassName UserControllerTest
 * @Author xuyisu
 * @Description 模拟http测试
 * @Date 2019/10/25
 */
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UserControllerTest {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
    }

    @Test
    public void whenGetUserInfoSuccess() throws Exception {
        String result = mockMvc.perform(get("/user/1")
                .contentType(MediaType.APPLICATION_JSON_UTF8))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.code").value(FwCommonConstants.SUCCESS))
                .andReturn().getResponse().getContentAsString();

        System.out.println(result);
    }
    //.......
    //具体请看代码`com.yisu.mock.UserControllerTest`

亲，点个star再走呗
