<result column="content" property="content" jdbcType="CLOB" javaType="string" typeHandler="com.cn.handler.OracleClobTypeHandler" />
处理器代码:
package com.cn.handler;
import java.sql.CallableStatement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import org.apache.ibatis.type.JdbcType;

public class OracleClobTypeHandler implements TypeHandler<Object>{
public Object valueOf(String param) {
return null;
}
@Override
public Object getResult(ResultSet arg0, String arg1) throws SQLException {
CLOB clob = (CLOB) arg0.getClob(arg1);
return (clob == null || clob.length() == 0) ? null : clob.getSubString((long) 1, (int) clob.length());
}
@Override
public Object getResult(ResultSet arg0, int arg1) throws SQLException {
return null;
}
@Override

}
@Override

}
}
插入时注意:
<insert>
insert into table(column,column...) values(value,value...)
</insert>
如果插入失败，则需要改成
<insert>
begin
insert into table(column,column...) values(value,value...)
;end;
</insert>
2、CLOB类型不支持的语法有
呃呃呃呃
