Use the struts Interceptor to implement the login verification function authorizationinterceptor

Some time ago, the project used the struts Interceptor to implement the login verification function, authorizationinterceptor. java.

 

Package Com. interceptor;

Import COM. opensymphony. xwork2.actioninvocation;
Import COM. opensymphony. xwork2.interceptor. *;
Import COM. opensymphony. xwork2. *;
Import JAVA. util. *;
/**

*/
Public class authorizationinterceptor extends extends actinterceptor {
private string ignoreactions;

//Getter method of the ignoreactions attribute
PublicString getignoreactios (){
ReturnIgnoreactions;
}

//Setter method of the ignoreactions attribute
Public VoidSetignoreactions (string ignoreactions ){
This. Ignoreactions = ignoreactions;
}

@ Override
PublicString intercept (actioninvocation Invocation)ThrowsException {
Actioncontext CTX = invocation. getinvocationcontext ();

Map session = CTX. getsession ();
String user = (string) Session. Get ("username ");

Boolean ignore = false ;
string currentaction = invocation. getproxy (). getactionname ();
string [] actions = ignoreactions. split (",");

For(String action: Actions ){
If(Currentaction. Matches (action. Trim ())){
Ignore =True;
Break;
}
}

If(User! =Null| Ignore =True){

ReturnInvocation. Invoke ();
}Else{
ReturnAction. login;
}

}
} Configure the interceptor in the Struts. xml file: < Interceptors >
< Interceptor Name = "Authorization" Class = "Com. Interceptor. authorizationinterceptor"   />
< Interceptor-Stack Name = "Mystack" >
< Interceptor-ref Name = "Authorization" >
< Param Name = "Ignoreactions" > Validate_code, register. *,. * login. *, upload, Connector </ Param >
</ Interceptor-ref > < Interceptor-ref Name = "Defaultstack"   />
</ Interceptor-Stack >
</ Interceptors >
< Default-interceptor-ref Name = "Mystack" />
