说明：可以通过定义全局结果来改变作用的范围，此外还可以通过在package中使用extends来继承，使用其被继承的东西

UserAction.java

<span style="font-size:18px;">package com.dqpi.eonline.action;

</span>
public int getType() {
return type;
}

public void setType(int type) {
this.type = type;
}

@Override
public String execute() throws Exception {
<span style="color:#ff0000;">if (type == 1) {
return "success";
} else if (type == 2) {
return "error";

return "mainPage";</span>
