集成Myabtis-Plus
//只須要繼承BaseMapper，就能實現單表的基本查詢
public interface UserMapper extends BaseMapper<User> {
List<User> listAll();
}
//繼承Model， ActiveRecord查詢方法
public class User extends Model<User> {
/**
* 定義一個承載， ActiveRecord,模仿自jFinal
*/
public static final User dao = new User();
private Long id;
private String nickname;
private String account;
private String password;
private String salt;
//timezone時區精度不要丟失
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private Date gmtCreate;
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private Date gmtModified;
//get and set...
@Override
protected Serializable pkVal() {
return this.id;
}
}
//查詢實例
@Service
public class IndexServiceImpl implements IndexService {
@Autowired
private UserMapper userMapper;
@Override
public List<User> mplist(String nickname) {
//傳統方式
List<User> list = userMapper.selectList(new EntityWrapper<User>().like("nickname", nickname));
//ActiveRecord
List<User> list1 = User.dao.selectList(new EntityWrapper<User>().like("nickname", nickname));
//上面兩種方法的結果是同樣的，不須要寫xml
return list;
}
}
集成Swagger2
@Configuration
@EnableSwagger2
@EnableWebMvc
@ComponentScan(basePackages = {"top.qwe666.spring5demo.controller"})
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any()).build().apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
Contact contact = new Contact("江笑GG", "qwe666.top", "jqw1122@foxmail.com");
return new ApiInfoBuilder()
.title("Demo")
.description("一個小荔枝")
.contact(contact)
.version("0.1")
.build();
}
}
<!-- 在spring-mvc.xml中 swagger2 config -->
<bean class="top.qwe666.spring5demo.common.SwaggerConfig"/>
<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
<mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>
以上說的都很簡單，不清晰的能夠看下源碼。mysql
