一、簡介
spring-boot-starter-web-servic是由Spring Boot官方提供的一個starter,主要用於構建基於SOAP協議的Web Services。它基於Spring Web Services,遵循了JAX-WS和JAXB規範。同時,它也提供了許多方便的特性,例如集成了Spring Security和Actuator。
二、集成使用
為了使用spring-boot-starter-web-servic,我們需要在pom.xml中添加以下依賴:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web-services</artifactId> </dependency>
接下來,我們可以使用@EnableWs註解開啟WebService支持,並使用@Endpoint註解來定義介面,例如:
@Configuration @EnableWs public class WebServiceConfig extends WsConfigurerAdapter { @Bean public ServletRegistrationBean messageDispatcherServlet(ApplicationContext context) { MessageDispatcherServlet servlet = new MessageDispatcherServlet(); servlet.setApplicationContext(context); servlet.setTransformWsdlLocations(true); return new ServletRegistrationBean(servlet, "/ws/*"); } @Bean(name = "hello") public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema schema) { DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition(); wsdl11Definition.setPortTypeName("HelloPort"); wsdl11Definition.setLocationUri("/ws"); wsdl11Definition.setTargetNamespace("http://example.com/hello"); wsdl11Definition.setSchema(schema); return wsdl11Definition; } @Bean public XsdSchema helloSchema() { return new SimpleXsdSchema(new ClassPathResource("hello.xsd")); } @PayloadRoot(namespace = "http://example.com/hello", localPart = "SayHelloRequest") @ResponsePayload public SayHelloResponse sayHello(@RequestPayload SayHelloRequest request) { SayHelloResponse response = new SayHelloResponse(); response.setMessage("Hello " + request.getName() + "!"); return response; } }
以上代碼中,我們配置了一個基於XSD Schema的WebService。通過向/messageDispatcherServlet的URL中添加請求參數,我們可以訪問該Webservice。
三、集成Spring Security
Spring Security可以有效地保護我們的WebService。我們可以使用Spring Security中提供的@Secured註解和@RolesAllowed註解來定義訪問控制。例如:
@Configuration @EnableWsSecurity public class WebServiceSecurityConfig extends WssConfigurerAdapter { @Autowired private UserDetailsService userDetailsService; @Autowired public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder()); } @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } @Override public void configure(WebSecurity web) throws Exception { web.ignoring().antMatchers("/ws/**"); } @Override public void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/ws/**").hasAnyRole("ADMIN", "USER") .anyRequest().authenticated() .and().httpBasic() .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS) .and().csrf().disable(); } @PayloadRoot(namespace = "http://example.com/hello", localPart = "SayHelloRequest") @Secured("ROLE_USER") @ResponsePayload public SayHelloResponse sayHello(@RequestPayload SayHelloRequest request, @AuthenticationPrincipal User user) { SayHelloResponse response = new SayHelloResponse(); response.setMessage("Hello " + request.getName() + " from " + user.getUsername() + "!"); return response; } }
以上代碼中,我們配置了基於角色的訪問控制,並使用@AuthenticationPrincipal註解來獲取當前用戶信息。此外,我們還禁用了CSRF保護,並對所有請求啟用了session。
四、集成Actuator
Actuator可以為我們提供一些有用的信息,例如應用程序的健康狀況和運行狀態。我們可以通過在pom.xml中添加對spring-boot-starter-actuator的依賴來啟用Actuator。例如:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>
啟用Actuator後,我們可以通過訪問/actuator/health或/actuator/info來獲取應用程序的健康狀況和一些基本信息。例如:
{ "status": "UP", "hello": { "status": "UP", "helloService": { "status": "UP", "description": "HelloService is running!" } }, "diskSpace": { "status": "UP", "total": 499963174912, "free": 169225228288, "threshold": 10485760 } }
五、總結
通過本文,我們詳細地介紹了spring-boot-starter-web-servic的使用方法,並且從集成Spring Security和Actuator兩個方面對其進行了更加深入的探討。通過使用spring-boot-starter-web-servic,我們可以輕鬆構建基於SOAP協議的Web Services,並為其提供全面的保護和管理。
