Question

我想检查authenticationProvider中的用户名和密码，但不知道为什么我无法调用authenticate方法。我正在通过spring security实现REST登录服务。我的web.xml是

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/applicationContext.xml
        WEB-INF/spring-security.xml</param-value>
</context-param>
<!-- Spring Security Filter  -->
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>
   org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
</filter>
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<servlet>
    <servlet-name>jersey-serlvet</servlet-name>
    <servlet-class>
        com.sun.jersey.spi.spring.container.servlet.SpringServlet
    </servlet-class>
    <init-param>
        <param-name>
            com.sun.jersey.config.property.packages
        </param-name>
        <param-value>com.zymr.ojo.action</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>jersey-serlvet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

<welcome-file-list>
    <welcome-file>jsp/login.jsp</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.jsp</welcome-file>
</welcome-file-list>

和spring-security.xml如下...

<context:component-scan base-package="com.zymr.ojo" />
<security:global-method-security pre-post-annotations="enabled" secured-     annotations="enabled" />

<!-- Security configuration for REST services. -->
<security:http use-expressions="true" entry-point-ref="restEntryPoint" create-  session="always">
    <!-- <security:http-basic/> -->
    <security:intercept-url pattern="/rest/question/**"  access="isAuthenticated()"/>
   <!--  <security:intercept-url pattern="/rest/login/userLogin" access="permitAll"/> -->
   <security:form-login login-processing-url="/rest/login/userLogin" username-parameter="admin" password-parameter="password"/>
</security:http>

<!-- Authentication manager. -->
<security:authentication-manager >
    <security:authentication-provider user-service-ref="authProvider" >
        </security:authentication-provider>
</security:authentication-manager>

<!-- Entry point for REST service. -->
<bean id="restEntryPoint" class="com.zymr.ojo.security.RestAuthenticationEntryPoint" />

<!-- A handler for successful REST service authentication. -->
<bean id="authSuccessHandler" class="com.zymr.ojo.security.RestAuthenticationSuccessHandler"></bean>
<bean id="authProvider" class="com.zymr.ojo.security.RestAuthenticationProvider" ></bean>

和RESTAuthenticationProvider类是

@Component公共类 RestAuthenticationProvider实现AuthenticationProvider，
的UserDetailsService {

public Authentication authenticate(Authentication authentication)
        throws AuthenticationException {
    System.out.println("in authProvider");
    String username = authentication.getName();
    String password = (String) authentication.getCredentials();
    if(username != null && password != null){
        System.out.println(username+ "  "+ password);
    }
    return null;
}

public boolean supports(Class<?> authentication) {
    // TODO Auto-generated method stub
    return false;
}

public UserDetails loadUserByUsername(String username)
        throws UsernameNotFoundException {
    System.out.println(username);
    return null;
}

}

Answer 1

问题在于supports(..)方法始终返回false。您的入口点应该为用户提供填充Authentication实例的方法，如果 supports方法返回true，这将被赋予authenticate方法。

Answer 2

请参阅以下链接。此链接指定添加UsernamePasswordAuthenticationFilter。我尝试了这个，但它没有调用login.html表单。

无法为登录REST服务调用spring安全性的验证方法
