struts hibernate getter setter方法冲突

| 分类 ssh学习  | 标签 struts  hibernate 

今天配置struts hibernate环境时遇到一个问题。 这是我的资源实体中的一个属性,get set方法使用eclipse generate 方法生成的。

private int pId;



<span class="kd">public</span> <span class="kt">int</span> <span class="nf">getpId</span><span class="o">()</span> <span class="o">{</span>
    <span class="k">return</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span>

<span class="kd">public</span> <span class="kt">void</span> <span class="nf">setpId</span><span class="o">(</span><span class="kt">int</span> <span class="n">pId</span><span class="o">)</span> <span class="o">{</span>
    <span class="k">this</span><span class="o">.</span><span class="na">pId</span> <span class="o">=</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span>
<span class="w">

可这样在表单中:

1
<input type="text" name="resource.pId">

总是在action中取不到pId的值，同时在后台保存一个new的resource是成功的。 后来才发现struts和hibernate对get set方法的要求存在一点不同。 eclipse的自动生成的get set 方法,hibernate是认可的。 struts则需要注意一点，就是类似于pId这样的命名，struts认可的set get方法是：

1

public void setPId(int pId) {
        this.pId = pId;
    }
    public int getPId() {
        return pId;
    }

所以最后的解决办法就是

1. 不嫌麻烦的可以写成这样

private int pId;



<span class="kd">public</span> <span class="kt">int</span> <span class="nf">getpId</span><span class="o">()</span> <span class="o">{</span>
    <span class="k">return</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span>

<span class="kd">public</span> <span class="kt">void</span> <span class="nf">setpId</span><span class="o">(</span><span class="kt">int</span> <span class="n">pId</span><span class="o">)</span> <span class="o">{</span>
    <span class="k">this</span><span class="o">.</span><span class="na">pId</span> <span class="o">=</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span>
<span class="kd">public</span> <span class="kt">void</span> <span class="nf">setPId</span><span class="o">(</span><span class="kt">int</span> <span class="n">pId</span><span class="o">)</span> <span class="o">{</span>
    <span class="k">this</span><span class="o">.</span><span class="na">pId</span> <span class="o">=</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span>
<span class="kd">public</span> <span class="kt">int</span> <span class="nf">getPId</span><span class="o">()</span> <span class="o">{</span>
    <span class="k">return</span> <span class="n">pId</span><span class="o">;</span>
<span class="o">}</span><span class="w">

2. 老老实实改属性名称，不要使用类似pId这样的。
