问题:

javax.servlet.jsp.JspException: No getter method for property rUnit of bean org.apache.struts.taglib.html.BEAN

NewForm.java
 

private String rUnit;   
   
public String getRUnit() {   
    return rUnit;   
}   
   
public void setRUnit(String rUnit) {   
    this.rUnit = rUnit;   
}   

 

 

New.jsp

 

运行，抛出上面提到的异常。

上网搜，CSDN找到相同问题的帖子，不过帖子最终也没道出问题的原因。不过帖子中的问题极相似，他的是eDate，我的是rUnit。他是把JSP中的eDate改成EDate就问题去除了。我在想，没道理啊，没有违反JAVA的编码规范啊，为什么要改。翻看前的Form Bean，啊，还真巧，以前的Form Bean中的属性名字都比较“长”的。而且都前面一节都非单字母：officePhone,而没写过oPhone之类的属性名。不会真因为这个吧，那两个字母呢，于是再试。。。。

结果出来了，两个（明显，是两个以上）小写字母打头就没问题。啊，这问题还让人想不明白，struts1.1在内部处理这些名字时应该是有问题的，起码根据JSP中的rUnit这个property名字不能正确地找到Form Bena里面相应的getRUnit()方法。但却能根据officePhone正确找到getOfficePhone()方法。

BUG，一定是个BUG。。。。

 

 

 

以前，相同的写法，运行正常！

 

OldForm.java

 

private String officePhone;   
   
public void setOfficePhone(String officePhone) {   
    this.officePhone = officePhone;   
}   
   
public String getOfficeAddress() {   
    return officeAddress;   
}   

 

 

Old.jsp

这是我在网上找到的　给大家分亨下
