Question

我开始使用Guice / Shiro而不是Spring / Spring Security。我查看了Shiro站点的示例，所有配置示例都是作为INI文件示例制作的。是否可以在普通Java中配置Shiro，因为要配置Guice Servlet？

是的，但是如果你想让Guice创建你的领域，需要一些胶水代码。

Bind Realm实施：

    bind(Realm.class).to(MyRealm.class).in(Singleton.class);

绑定WebSecurityManager：

    @Provides @Singleton WebSecurityManager securityManager(Realm realm) {
      DefaultWebSecurityManager sm = new DefaultWebSecurityManager();
      sm.setRealm(realm);
      return sm;
    }

Shiro过滤器的一个子类，因此您可以使用Guice提供的WebSecurityManager：

    public class SecurityFilter extends IniShiroFilter {

      static class SecurityManagerFactory extends WebIniSecurityManagerFactory {

        private final WebSecurityManager securityManager;

        public SecurityManagerFactory(WebSecurityManager securityManager) {
          this.securityManager = securityManager;
        }

        public SecurityManagerFactory(WebSecurityManager securityManager, Ini ini) {
          super(ini);
          this.securityManager = securityManager;
        }

        @Override
        protected SecurityManager createDefaultInstance() {
          return securityManager;
        }
      }

      private final Provider<WebSecurityManager> securityManager;

      @Inject
      SecurityFilter(Provider<WebSecurityManager> securityManager) {
        super();
        this.securityManager = securityManager;
      }


      protected Map<String, ?> applySecurityManager(Ini ini) {
        SecurityManagerFactory factory;
        if (ini == null || ini.isEmpty()) {
          factory = new SecurityManagerFactory(securityManager.get());
        } else {
          factory = new SecurityManagerFactory(securityManager.get(), ini);
        }
        setSecurityManager((WebSecurityManager) factory.getInstance());
        return factory.getBeans();
      }
    }

配置过滤器：

    Joiner lines = Joiner.on("\n");
    Map<String, String> config = ImmutableMap.of("config", lines.join(
        "; here you can provide additional ini",
        "[roles]",
        "admin = *",
        "[urls]",
        "/secure/** = authcBasic"
    ));
    filter("/*").through(SecurityFilter.class, config);

使用Google Guice Servlet配置Apache Shiro
