struts配置数据源

在struts-config.xml文件增加新节点

xml 代码

<data-sources>
    <data-source type="org.apache.commons.dbcp.BasicDataSource">
        <set-property value="com.mysql.jdbc.Driver" property="driverClassName" />
<set-property value="jdbc:mysql://localhost:3306/db_mysql" property="url" />
<set-property value="root" property="username" />
<set-property value="" property="password" />
<set-property property="driverClass" value="true"/>
<set-property property="readOnly" value="false"/>
<set-property property="autoCommit" value="false"/>
<set-property property="minCount" value="1"/>
<set-property property="maxCount" value="10"/>
/data-source>
data-sources>

 

并在Action文件中增加以下内容：

java 代码

public ActionForward execute(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response) {
    // TODO Auto-generated method stub

        javax.sql.DataSource ds = getDataSource(request);
        Connection conn = null;
        ResultSet rs = null;
        Statement st = null;
        try{
            conn = ds.getConnection();
            st = conn.createStatement();
            rs = st.executeQuery("select * from user01");
            request.setAttribute("rs", rs);
        }catch(Exception e){
            e.printStackTrace();
        }
    return mapping.findForward("forward");
}
