我试图注入阿帕奇四郎使用，但...我得到空我的自定义AuthorizingRealm里面我的UserDAO。
我究竟做错了什么？
shiro.ini
[main]
user = demo.shiro.security.FacesAjaxAwareUserFilter
realmA = demo.shiro.security.JpaRealm
credentialsMatcher = org.apache.shiro.authc.credential.SimpleCredentialsMatcher
realmA.credentialsMatcher = $credentialsMatcher
securityManager.realms = $realmA
user.loginUrl = /pages/public/login.xhtml
[users]
admin = admin
user = user
[urls]
# public files and folders
/index.html = anon
/resources/** = anon
/pages/public/** = anon
# restricted files and folders
/pages/admin/** = user
/pages/user/** = user
JpaRealm.java
public class JpaRealm extends AuthorizingRealm {
@Inject
private UserDao userDao;
public JpaRealm() {
setCredentialsMatcher(new Sha256CredentialsMatcher());
}
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authToken) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) authToken;
User user = userDao.getForUsername(token.getUsername());
if (user != null) {
return new SimpleAuthenticationInfo(user.getId(), user.getPassword(), getName());
} else {
return null;
}
}
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
Long userId = (Long) principals.fromRealm(getName()).iterator().next();
User user = userDao.findByKey(userId);
if (user != null) {
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
for (Role role : user.getRoles()) {
info.addRole(role.getDescription());
for (Permition permition : role.getPermitions()) {
info.addStringPermission(permition.getDescription());
}
}
return info;
} else {
return null;
}
}
}
我必须做的，让CDI要意识到@Inject我的自定义领域内，妥善注入我的UserDAO？
由阿帕奇四郎使用的默认EnvironmentLoaderListener不知道CDI。 该解决方案是构建一个是和替换在web.xml中的原始参考点为您量身定制的。
注：CDI注入支持的听众自动 ，但听者必须通过CDI机制要求豆类。 自定义监听器将使用@Inject请求豆类和将创造JpaRealm为CDI豆，这将有注入的依赖关系。 默认郡听众不会造成JpaRealm为通过启用CDI豆@Inject 。
CustomCredentialsMatcher.java
public class CustomCredentialsMatcher extends SimpleCredentialsMatcher {
}
CustomEnvironmentLoaderListener.java
public class CustomEnvironmentLoaderListener extends EnvironmentLoaderListener {
@Inject
private JpaRealm jpaRealm;
@Override
protected WebEnvironment createEnvironment(ServletContext pServletContext) {
WebEnvironment environment = super.createEnvironment(pServletContext);
RealmSecurityManager rsm = (RealmSecurityManager) environment.getSecurityManager();
PasswordService passwordService = new DefaultPasswordService();
PasswordMatcher passwordMatcher = new PasswordMatcher();
passwordMatcher.setPasswordService(passwordService);
jpaRealm.setCredentialsMatcher(passwordMatcher);
rsm.setRealm(jpaRealm);
((DefaultWebEnvironment) environment).setSecurityManager(rsm);
return environment;
}
}
FacesAjaxAwareUserFilter.java
public class FacesAjaxAwareUserFilter extends UserFilter {
private static final String FACES_REDIRECT_XML = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><partial-response><redirect url=\"%s\"></redirect></partial-response>";
@Override
protected void redirectToLogin(ServletRequest req, ServletResponse res) throws IOException {
HttpServletRequest request = (HttpServletRequest) req;
if ("partial/ajax".equals(request.getHeader("Faces-Request"))) {
res.setContentType("text/xml");
res.setCharacterEncoding("UTF-8");
res.getWriter().printf(FACES_REDIRECT_XML, request.getContextPath() + getLoginUrl());
} else {
super.redirectToLogin(req, res);
}
}
}
JpaRealm.java
public class JpaRealm extends AuthorizingRealm {
private static String REALM_NAME = "jpaRealm";
@Inject
private UserDao userDao;
@Inject
private RoleDao roleDao;
@Inject
private PermissionDao permissionDao;
public JpaRealm() {
setName(REALM_NAME); // This name must match the name in the User class's getPrincipals() method
}
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authToken) throws AuthenticationException {
UsernamePasswordToken token = (UsernamePasswordToken) authToken;
User user = userDao.getForUsername(token.getUsername());
if (user != null) {
return new SimpleAuthenticationInfo(user.getId(), user.getPassword(), getName());
} else {
return null;
}
}
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
Long userId = (Long) principals.fromRealm(getName()).iterator().next();
User user = userDao.findByKey(userId);
if (user != null) {
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
for (Role role : roleDao.getForUser(user)) {
info.addRole(role.getDescription());
for (Permition permition : permissionDao.getForRole(role)) {
info.addStringPermission(permition.getDescription());
}
}
return info;
} else {
return null;
}
}
}
shiro.ini
[main]
user = com.boss.mrfoods.security.FacesAjaxAwareUserFilter
user.loginUrl = /pages/public/login.xhtml
[urls]
/index.html = anon
/pages/index.xhtml = anon
/pages/public/** = anon
/pages/admin/** = user, roles[ADMIN]
/pages/user/** = user, roles[USER]
web.xml中
...
<listener>
<listener-class>com.boss.mrfoods.security.CustomEnvironmentLoaderListener</listener-class>

jpaRealm是碰巧在“CustomEnvironmentLoaderListener”空。 我试图建立@Service（“JpaRealm”）标注上JpaRealm类以及使容器可以知道注射，但仍然没有运气。 JpaRealm是在两种情况下空。
是还有什么必要的情况下做我们蚂蚁注射自定义领域工作。
使用ShiroWebModule注入您的自定义域
public class PocShiroModule extends ShiroWebModule {
public PocShiroModule(ServletContext servletContext) {
super(servletContext);
}
@Override
protected void configureShiroWeb() {
bindConstant().annotatedWith(Names.named("shiro.globalSessionTimeout"))
.to(30000L);
bind(Realm.class).to(JPARealm.class);
}
@Provides
@Singleton
Set<Realm> provideRealmSet(Realm realm) {
Set<Realm> result = new HashSet<Realm>();
result.add(realm);
return result;
}
}
在您的上下文监听器注册该模块
public class PocGuiceServletConfig extends GuiceServletContextListener {
private ServletContext context = null;
@Override
public void contextInitialized(ServletContextEvent servletContextEvent) {
this.context = servletContextEvent.getServletContext();
super.contextInitialized(servletContextEvent);
}
@Override
protected synchronized Injector getInjector() {
return Guice.createInjector(
new PocModule(),
new PocShiroModule(context),
new ShiroAopModule());
}
}
