1、Hibernate+MySQL 中文问题解决方案：MySQL安装时设置字符集utf-8, jdbc驱动3.0.15以上.

2. hibernate配置文件中,加上属性

<ol class="dp-xml">
<li class="alt"><span><span class="tag"><span class="tag-name">property</span><span> </span><span class="attribute">name</span><span>=</span><span class="attribute-value">"connection.useUnicode"</span><span class="tag">></span><span>true</span><span class="tag"></span><span class="tag-name">property</span><span class="tag">></span><span>   </span></span></span></li>
<li><span class="tag"><span class="tag-name">property</span><span> </span><span class="attribute">name</span><span>=</span><span class="attribute-value">"connection.characterEncoding"</span><span class="tag">></span><span>UTF-8</span><span class="tag"></span><span class="tag-name">property</span><span class="tag">></span><span>  </span></span></li>
</ol>

3. web.xml设置Filter
 

<ol class="dp-xml">
<li class="alt"><span><span class="tag"><span class="tag-name">filter</span><span class="tag">></span><span>   </span></span></span></li>
<li><span class="tag"><span class="tag-name">filter-name</span><span class="tag">></span><span>   </span></span></li>
