实体对应XML更新

在POJO类中，重写toString方法

@Override
    public String toString()
    {
         String ret = "";
            ret = "  <Unit>/n";
            ret = (new StringBuilder(String.valueOf(ret))).append("    <UnitID>").append(unitid).append("</UnitID>/n").toString();      
            ret = (new StringBuilder(String.valueOf(ret))).append("    <UnitName><![CDATA[").append(unitname).append("]]></UnitName>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Panel><![CDATA[").append(panel).append("]]></Panel>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Panel_type>").append(paneltype).append("</Panel_type>/n").toString();          
            ret = (new StringBuilder(String.valueOf(ret))).append("    <LogicalX>").append(logicalx).append("</LogicalX>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <LogicalY>").append(logicaly).append("</LogicalY>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Coord_point>").append(coordpoint).append("</Coord_point>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Singleormore>").append(singleormore).append("</Singleormore>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Desc><![CDATA[").append(discription).append("]]></Desc>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <LogoPic><![CDATA[").append(logopic).append("]]></LogoPic>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Img><![CDATA[").append(unitinfo==null?"":unitinfo).append("]]></Img>/n").toString();          
            ret = (new StringBuilder(String.valueOf(ret))).append("    <Company><![CDATA[").append(companyinfo==null?"":companyinfo).append("]]></Company>/n").toString();
            ret = (new StringBuilder(String.valueOf(ret))).append("  </Unit>/n").toString();
            return ret;
    }

//注意标签：<Img></Img>解释：该实体关联的图片，<Company><Company/>解释：在该实体里，所入住的公司，

//<Company><![CDATA[ ,0]]></Company>可以是这样 <Company><![CDATA[ xzy,72]]></Company>
