@ControllerAdvice
@CookieValue,
@CrossOrigin,
@DeleteMapping,
@ExceptionHandler,
@GetMapping,
@InitBinder,
@Mapping,
@MatrixVariable,
@ModelAttribute,
@package,-info
@PatchMapping,
@PathVariable,
@PostMapping,

/*** 参数类型转换错误** @param e* @return*/
@ExceptionHandler(ConversionException.class)
public Object conversionException(ConversionException e) {
log.error(">>>异常：{}", JSONObject.toJSONString(e));
e.printStackTrace();
return ResultBean.error(HttpStatus.BAD_REQUEST.value() + "", e.getMessage());
}
}
@SessionAttribute,
@SessionAttributes,
@SessionScope
@RequestScope
@ApplicationScope
这三个定义实例对象的时候，实例化方式，和Singleton
二、spring-context
@Bean
@ComponentScan，可用于扫描Model,多模块的开发中会用到
@ComponentScans
@Conditional
@Configuration
@DependsOn
@Description
@EnableAspectJAutoProxy
@EnableLoadTimeWeaving
@EnableMBeanExport
@Import
使用格式如下
@Configuration
public class ConfigA {@Beanpublic A a() {return new A();}
}@Configuration
public class ConfigB {@Beanpublic B b() {return new B();}
}@Configuration
@Import(value = {ConfigA.class, ConfigB.class})
public class ConfigD {@Beanpublic D d() {return new D();}
}
@ImportResource
@Lazy
@Primary，定义多个数据源的时候，
@Configuration
public class DataSourceConfig {// 默认数据源 DB-1@Bean(name = "dataSourceCore")@ConfigurationProperties(prefix = "spring.datasource") // application.properteis中对应属性的前缀public DataSource dataSourceCore() {return DruidDataSourceBuilder.create().build();}// 数据源-DB-2@Bean(name = "dataSourceBiz")@ConfigurationProperties(prefix = "biz.datasource") // application.properteis中对应属性的前缀public DataSource dataSourceBiz() {return DruidDataSourceBuilder.create().build();}/*** 动态数据源: 通过AOP在不同数据源之间动态切换@SuppressWarnings({"rawtypes", "unchecked"})@Primary@Bean(name = "dynamicDataSource")public DataSource dynamicDataSource() {DynamicDataSource dynamicDataSource = new DynamicDataSource();// 默认数据源dynamicDataSource.setDefaultTargetDataSource(dataSourceCore());// 配置多数据源Map<Object, Object> dsMap = new HashMap();dsMap.put("dataSourceCore", dataSourceCore());dsMap.put("dataSourceBiz", dataSourceBiz());dynamicDataSource.setTargetDataSources(dsMap);return dynamicDataSource;}
}
@Profile
@PropertySource
@PropertySources
@Role
@Scope,这个值用于标注，单例或者prototype等
@ScopeMetadataResolver
@DateTimeFormat,用于Model定义时的，String 转LocalDateTime,前端 传时间类型 xxxx-xx-xx xx:xx:xx,可转成LocaldateTime(2011-12-13T12:46:36)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")private LocalDateTime tradeDate;
@NumberFormat,可用于decimal的数值，转换,前端可传值(逗号分隔的数字)11,314.314可转成11314.314
@NumberFormat(pattern = "#,###,###,###.##")private BigDecimal amount;
@Component，标注组件（自动扫描），很多常见的@Controller，@Service，@Repository,@Configuration等都注入了这个注解
@Controller
@Indexed
@Repository，定义Dao层，注意和@NoRepositoryBean的配合使用（公共Repo的时候会用到）
@Service，常用于标注在接口实现类上，还有异步接口的管理(使用时注入UserService，就可调度此异步的具体实现)
@Service
public class UserService {private static final Logger logger = LoggerFactory.getLogger(UserService.class);private final RestTemplate restTemplate;public UserService(RestTemplateBuilder restTemplateBuilder) {this.restTemplate = restTemplateBuilder.build();}@Async("task1")public CompletableFuture <User> findUser(String user) throws InterruptedException {logger.info("Looking up " + user);String url = String.format("api.github./users/%s", user);User results = restTemplate.getForObject(url, User.class);//Thread.sleep(1000L);return CompletableFuture.pletedFuture(results);}
}
@Async
@EnableAsync
@EnableScheduling
@Scheduled
@Schedules
@EventListener,事件监听，在微服务的学习中，我用这个注解，打印了所有已注册的服务名
package .example.bootiful.ponent;import lombok.extern.log4j.Log4j2;
import .springframework.boot.context.event.ApplicationReadyEvent;
import .springframework.cloud.client.discovery.DiscoveryClient;
import .springframework.context.event.EventListener;
import .springframework.stereotype.Component;@Log4j2
@Component
public class DiscoveryClientListener {private final DiscoveryClient discoveryClient;public DiscoveryClientListener(DiscoveryClient discoveryClient) {this.discoveryClient = discoveryClient;}@EventListener(ApplicationReadyEvent.class)public void useDiscoveryClient() {this.discoveryClient.getServices().forEach(log::info);}

九、springboot.context

tonels:duckName: tonels configration testtotalCount: 2server:servlet:context-path: /tonelsport: 8081
注入时
@Configuration
@ConfigurationProperties(prefix="tonels")
@Data
public class DuckPorperties{private String duckName;private int totalCount;
}
使用时
@RequestMapping("/duck")public String duck() {/*** 自动装配模式的配置文件属性。*/return duckPorperties.getDuckName();}
@ConfigurationPropertiesBinding
@DeprecatedConfigurationProperty

@Id
@LastModifiedBy
@LastModifiedDate
@package-info
@PersistenceConstructor
@Persistent
@QueryAnnotation
@ReadOnlyProperty
@Reference
@Transient
@TypeAlias
@Version,JPA中乐观锁的实现
定义在字段上，
@Version
private int version;
@NoRepositoryBean
@NoRepositoryBean，定义公共库的时候，会用到
public interface BaseRepository<T> extends JpaRepository<T, Long>, JpaSpecificationExecutor<T>{}
@RepositoryDefinition
十一、spring-cloud-mon
@EnableCircuitBreaker
@EnableDiscoveryClient，定义在启动类上，作用于服务的注册与发现，启动会把该项目注册到注册中心
@SpringBootApplication
@EnableDiscoveryClient
public class Ams1Application {public static void main(String[] args) {SpringApplication.run(Ams1Application.class, args);}
}
此处是，引自基于alibaba 的springcloud 的微服务实现的服务的注册和发现。
@LoadBalanced,这个注解是在微服务间的调用过程中，可能会使用到这个注解（微服务间多种调用方式，这个不是必须的）,关于其他的调用方式可以参考这个，点击这个
@EnableDiscoveryClient
@SpringBootApplication
public class Application {@Bean@LoadBalancedpublic RestTemplate restTemplate() {return new RestTemplate();}public static void main(String[] args) {SpringApplication.run(Application.class);}
}
使用的时候，
@AutowiredRestTemplate restTemplate;@GetMapping("/consumer")public String dc() {return restTemplate.getForObject("eureka-client/client", String.class);}
@SpringCloudApplication
十二、spring-cloud.context

@UseSpelInvoker
@EnableIntegration
@EnableIntegrationManagement
@EnableMessageHistory
@EnablePublisher
@GlobalChannelInterceptor
@IntegrationConverter
@IntegrationManagedResource
@SecuredChannel
十八、spring.webMvc
@EnableWebMvc，常在Spring + JSP中使用
这里用于定义web资源，路径（相对和绝对路径）
@Configuration
@EnableWebMvc
@ComponentScan(".book.web")
public class WebConfig extends WebMvcConfigurerAdapter {@Beanpublic ViewResolver viewResolver() {InternalResourceViewResolver resolver = new InternalResourceViewResolver();resolver.setPrefix("/WEB-INF/views/");resolver.setSuffix(".jsp");return resolver;}@Overridepublic void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {configurer.enable();}@Overridepublic void addResourceHandlers(ResourceHandlerRegistry registry) {registry.addResourceHandler("/img/**").addResourceLocations("/static/images/");registry.addResourceHandler("/js/**").addResourceLocations("/static/js/");registry.addResourceHandler("/css/**").addResourceLocations("/static/css/");registry.addResourceHandler("/html/**").addResourceLocations("/static/html/");}
}
十九、spring-cloud-openfeign-core，这个包用于远程过程调用的时候引入
@EnableFeignClients,启动类上注解
@SpringBootApplication
@EnableFeignClients
@EnableDiscoveryClient
public class OpenFeinApplication {public static void main(String[] args) {SpringApplication.run(OpenFeinApplication.class, args);}
}
@FeignClient，定义在远程过程调用中的接口上
@FeignClient(name = "AMS1",fallback = RemoteHystrix.class)
public interface RemoteClient {@GetMapping("/ams1/open")String openFeign();
}
这个调用类似请求，AMS1:注册port/ams1/open
@SpringQueryMap
二十、spring-security-config
@EnableGlobalAuthentication
@EnableGlobalMethodSecurity
@EnableWebSecurity
在spring security中需要这样的配置，去做系统权限的管理
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends JsonWebTokenSecurityConfig {@Overrideprotected void setupAuthorization(HttpSecurity http) throws Exception {http.authorizeRequests()// allow anonymous aess to /user/login endpoint.antMatchers("/user/login").permitAll().antMatchers("/swagger/**").permitAll().antMatchers("/web/**").permitAll().antMatchers("/").permitAll()// authenticate all other requests.anyRequest().authenticated();}
}
@EnableWebMvcSecurity
