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。
