我遵循了关于如何在 Struts2 中使用通配符技术的在线教程，但它并不像显示的那样工作。在执行命令时，它只调用 execute() 方法，从不调用任何其他方法。我不确定问题是什么，但任何帮助都会很棒。
下面是我的 Action 文件和将 Action 链接到 JSP 页面上的 JSP 调用的 struts 文件。
CalculatorAction.java
package com.simplecode.action;
import com.opensymphony.xwork2.ActionSupport;
public class CalculatorAction extends ActionSupport
{
private float number1;
private float number2;
private float result;
private String methodName;
public String add()
{
System.out.print("afsnjfbkjsdfhdskfhsdkjfhksdjfhkdsjfhksdjfhsdkjfhksjfhkjdsfhdsk");
result=number1+number2;
setMethodName("add Method");
return SUCCESS;
}
public String subtract()
{
result = number1 - number2;
setMethodName("subtract Method");
return SUCCESS;
}
public String multiply()
{
result = number1 * number2;
setMethodName("multiply Method");
return SUCCESS;
}
public String divide()
{
if(number2!=0)
result = number1/number2;
else if(number1!=0)
result = number2/number1;
else
result=0;
setMethodName("divide Method");
return SUCCESS;
}
public float getNumber1() {
return number1;
}
public void setNumber1(float number1) {
this.number1 = number1;
}
public float getNumber2() {
return number2;
}
public void setNumber2(float number2) {
this.number2 = number2;
}
public float getResult() {
return result;
}
public void setResult(float result) {
this.result = result;
}
public String getMethodName() {
return methodName;
}
public void setMethodName(String methodName) {
this.methodName = methodName;
}
}
