在Spring 4中配置不带XML的Spring Security

Question

我想用一个custom authentication filter:

1. 捕获加密的标头令牌
2. 验证之后,提取用户的详细信息,并以无状态方式将它们添加到当前请求的安全上下文中

我希望能够使用此安全上下文持有者来获取有关当前请求用户正确处理其请求的详细信息.

@RequestMapping(value = "/simple", method = RequestMethod.POST)
@ResponseBody
@Transactional
@Preauthorize(...)
public String simple(){
   //collect the user's current details from the getPrinciple() and complete the transaction...
    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
    return "Simple";
}

我以前用XML做过这样的事情:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.2.xsd">

    <security:global-method-security
        secured-annotations="enabled" />

    <security:http pattern="/**"
        auto-config="true" disable-url-rewriting="true" use-expressions="true">
        <security:custom-filter ref="authenticationTokenProcessingFilter"
            position="FORM_LOGIN_FILTER" />
        <security:intercept-url pattern="/authenticate"
            access="permitAll" />
        <security:intercept-url pattern="/secure/**"
            access="isAuthenticated()" />
    </security:http>

    <bean id="CustomAuthenticationEntryPoint" class="org.foo.CustomAuthenticationEntryPoint" />

    <bean class="org.foo.AuthenticationTokenProcessingFilter" id="authenticationTokenProcessingFilter">
        <constructor-arg ref="authenticationManager" />
    </bean>

</beans>

但是,我希望这可以Spring Boot在非xml WebSecurityConfigurerAdapter中使用更新的应用程序,就像它们的Spring Boot文件中的示例一样:

    @Bean
    public ApplicationSecurity applicationSecurity() {
        return new ApplicationSecurity();
    }

    @Order(Ordered.LOWEST_PRECEDENCE - 8)
    protected static class ApplicationSecurity extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // this is obviously for a simple "login page" not a custom filter!
http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin()
                        .loginPage("/login").failureUrl("/login?error").permitAll(); 
            }
        }

有什么建议或类似的例子吗？

我现在正在做类似的事情。将来有人可能会发现这很有帮助。将 xml 转换为 java 配置将使其如下所示：

import javax.servlet.Filter;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.AuthenticationEntryPoint;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@EnableGlobalMethodSecurity(securedEnabled=true) //<security:global-method-security secured-annotations="enabled" />
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("authenticationTokenProcessingFilter")
    private Filter authenticationTokenProcessingFilter;

    @Autowired
    private AuthenticationEntryPoint entryPoint;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.exceptionHandling().authenticationEntryPoint(entryPoint);


        http //auto-config="true"
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .and()
            .httpBasic();


        http
            .authorizeRequests() // use-expressions="true"
            .antMatchers("/authenticate").permitAll() //<security:intercept-url pattern="/authenticate" access="permitAll" />
            .antMatchers("/secure/**").authenticated() //<security:intercept-url pattern="/secure/**"            access="isAuthenticated()" />
            .and()
            .addFilterBefore(authenticationTokenProcessingFilter, UsernamePasswordAuthenticationFilter.class) // <security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" /> http://docs.spring.io/spring-security/site/docs/3.0.x/reference/ns-config.html
            ;
    }
}
