public class commonrealm extends authorizingrealm {

private userloginservice userloginservice;
@override
public string getname() {
return "commonrealm";
}
//授权
@override
protected authorizationinfo dogetauthorizationinfo(principalcollection principals) {
string usernmae = (string) principals.getprimaryprincipal();
list<string> permissions = new arraylist<string>();
if ("admin".equals(usernmae)) {
permissions.add("admin:ee");
}
simpleauthorizationinfo info = new simpleauthorizationinfo();
info.addstringpermissions(permissions);
return info;
}
//身份认证
@override
protected authenticationinfo dogetauthenticationinfo(authenticationtoken token) throws authenticationexception {
string username = (string) token.getprincipal();
user user = userloginservice.getuser(username);
if (user == null) {
return null;
}
simpleauthenticationinfo info = new simpleauthenticationinfo(username, user.getpassword(), getname());
return info;
}
}

@controller
public class useraction {
@autowired
private userloginservice userloginservice;
@requestmapping("/login.do")
public string userlogin(httpservletrequest request, string username, string password) throws exception {
// 如果登陆失败从request中获取异常信息，shirologinfailure就是shiro异常类的全限定名
string exceptionclassname = (string) request.getattribute("shirologinfailure");
if (exceptionclassname != null) {
if (unknownaccountexception.class.getname().equals(exceptionclassname)) {
// 最终会抛给异常处理器
throw new xxxexception("用户名不存在");
} else if (incorrectcredentialsexception.class.getname().equals(exceptionclassname)) {
throw new xxxexception("用户名/密码错误");
} else {
throw new exception();// 最终在异常处理器生成未知错误
}
}
// 如果登录成功的话不走此方法，shiro认证成功会自动跳转到上一个请求路径，配的的successurl没效果，后边会说
// 登陆失败走此方法，捕获异常，然后 return ~ ,还到login页面
return "login.jsp";
}
}

3、检测权限 controller

//此方法为了验证权限是否生效
@requestmapping("/findall.do")
@requirespermissions("admin:ee")
public modelandview list(httpservletrequest request){
.......
}
|
三、常见问题
因为有一些特别常见的问题，需要修改xml配置，所以现在先手问题，把xml配置放在后边，直接就配置完善好的xml
问题一：登陆成功后shiro默认跳到上一次请求，没有上一次请求默认跳到/ ，那我们就想控制调到自己定义的路径咋办呢？
解决方案：
步骤一：继承formauthenticationfilter类，重写onloginsuccess方法，这里可以自定义路径，因为这里自定义了成功跳转的路径，所以配置里的successurl不用配置，赔了也没效果。。

public class loginsuccesstofilter extends formauthenticationfilter {
@override
protected boolean onloginsuccess(authenticationtoken token, subject subject, servletrequest request, servletresponse response) throws exception {
webutils.getandclearsavedrequest(request);
webutils.redirecttosavedrequest(request,response,"/findall.do");
return false;
}
}
|
步骤二：
在shiro的xml配置文件中配置
|
1
|
<bean id="myfilter" class="com.xxx.realm.loginsuccesstofilter"></bean>
|
在 shirofilter配置中引入,完整xml在后边
