package com.example.actions;

import com.opensymphony.xwork2.ActionSupport; 
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Actions;

public class HelloWorld extends ActionSupport {
  @Action("/different/url")
  public String execute() {
    return SUCCESS;
  }

  @Action("url")
  public String doSomething() {
    return SUCCESS;
  }
}

This The previous example defines a second URL that is not fully qualified. This means that the namespace for the URL is determined using the Java package name rather than the Action annotation.

Result(s) annotation

Interceptor and interceptor stacks can be specified using the interceptorRefs attribute. The following example applies the "validation" interceptor and the "defaultStack" interceptor stack to the action:

package com.example.actions;

import com.opensymphony.xwork2.ActionSupport; 
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Actions;

public class HelloWorld extends ActionSupport {
  @Action(interceptorRefs={@InterceptorRef("validation"), @InterceptorRef("defaultStack")})
  public String execute() {
    return SUCCESS;
  }

  @Action("url")
  public String doSomething() {
    return SUCCESS;
  }
}

Parameters can be passed to results using the params attribute. The value of this attribute is a string array with an even number of elements in the form {"key0", "value0, "key1", "value1" ... "keyN", "valueN"}. For example:

package com.example.actions;

import com.opensymphony.xwork2.ActionSupport; 
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Actions;

public class HelloWorld extends ActionSupport {
  @Action(interceptorRefs=@InterceptorRef(value="validation",params={"programmatic", "false", "declarative", "true}))
  public String execute() {
    return SUCCESS;
  }

  @Action("url")
  public String doSomething() {
    return SUCCESS;
  }
}

If interceptors are not specified, the default stack is applied.

Result(s) annotation

The Convention plugin allows action classes to define different results for an action. Results fall into two categories, global and local. Global results are shared across all actions defined within the action class. These results are defined as annotations on the action class. Local results apply only to the action method they are defined on. Here is an example of the different types of result annotations:

package com.example.actions;

import com.opensymphony.xwork2.ActionSupport; 
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Actions;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;

@Results({
  @Result(name="failure", location="fail.jsp")
})
public class HelloWorld extends ActionSupport {
  @Action(value="/different/url", 
    results={@Result(name="success", location="http://struts.apache.org", type="redirect")}
  )
  public String execute() {
    return SUCCESS;
  }

  @Action("/another/url")
  public String doSomething() {
    return SUCCESS;
  }
}

Parameters can be passed to results using the params attribute. The value of this attribute is a string array with an even number of elements in the form {"key0", "value0, "key1", "value1" ... "keyN", "valueN"}. For exampleThe Convention plugin allows action classes to define different results for an action. Results fall into two categories, global and local.

public class HelloWorld extends ActionSupport {
  @Action(value="/different/url", 
    results={@Result(name="success", locationtype="http://struts.apache.orghttpheader", type="redirect"params={"status", "500", "errorMessage", "Internal Error"})}
  )
