一、简介
spring-boot-starter-web-servic是由Spring Boot官方提供的一个starter,主要用于构建基于SOAP协议的Web Services。它基于Spring Web Services,遵循了JAX-WS和JAXB规范。同时,它也提供了许多方便的特性,例如集成了Spring Security和Actuator。
二、集成使用
为了使用spring-boot-starter-web-servic,我们需要在pom.xml中添加以下依赖:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web-services</artifactId> </dependency>
接下来,我们可以使用@EnableWs注解开启WebService支持,并使用@Endpoint注解来定义接口,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; } }
以上代码中,我们配置了一个基于XSD Schema的WebService。通过向/messageDispatcherServlet的URL中添加请求参数,我们可以访问该Webservice。
三、集成Spring Security
Spring Security可以有效地保护我们的WebService。我们可以使用Spring Security中提供的@Secured注解和@RolesAllowed注解来定义访问控制。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; } }
以上代码中,我们配置了基于角色的访问控制,并使用@AuthenticationPrincipal注解来获取当前用户信息。此外,我们还禁用了CSRF保护,并对所有请求启用了session。
四、集成Actuator
Actuator可以为我们提供一些有用的信息,例如应用程序的健康状况和运行状态。我们可以通过在pom.xml中添加对spring-boot-starter-actuator的依赖来启用Actuator。例如:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency>
启用Actuator后,我们可以通过访问/actuator/health或/actuator/info来获取应用程序的健康状况和一些基本信息。例如:
{ "status": "UP", "hello": { "status": "UP", "helloService": { "status": "UP", "description": "HelloService is running!" } }, "diskSpace": { "status": "UP", "total": 499963174912, "free": 169225228288, "threshold": 10485760 } }
五、总结
通过本文,我们详细地介绍了spring-boot-starter-web-servic的使用方法,并且从集成Spring Security和Actuator两个方面对其进行了更加深入的探讨。通过使用spring-boot-starter-web-servic,我们可以轻松构建基于SOAP协议的Web Services,并为其提供全面的保护和管理。
