本文介绍了一个关于使用Ibatis框架返回字符串时遇到的错误及其解决方案。主要问题出现在jdbcType属性设置上，应将其从varchar更改为VARCHAR以确保正确执行。

通过Ibatis返回一个字符串；一直报错！配置如下：
sqlMap：
<parameterMap id="pm_in_applyKobei" class="java.util.Map">
<parameter property="userId" javaType="int" jdbcType="INTEGER" mode="INOUT" />
<parameter property="rtnStr" javaType="string" jdbcType="varchar" mode="INOUT" />
</parameterMap>
<procedure id="duankoo_validKooBei" parameterMap="pm_in_applyKobei">
{call duankoo_validKooBei(?,?)}
</procedure>

procedure：已经在分析器里面调试通过；

javaCode：
public String applyKoBei(Integer userId) {
String rtnStr = "";
HashMap map = new HashMap();
map.put("userId", 2);
map.put("rtnStr", rtnStr);
this.getSqlMapClientTemplate().queryForObject("integral.duankoo_validKooBei",map);
return (String)map.get("rtnStr");
}

一直报错：
Exception in thread "main" org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation; uncategorized SQLException for SQL []; SQL state [HY092]; error code [0];
