今天配置typehandler时碰到一个问题
主要解决的问题是
java.sql.SQLException: Cannot convert value '0000-00-00 00:00:00' from column 18 to TIMESTAMP
解决方案: 替换掉系统默认的 typehandler, 抛出异常时,改为null
<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<settings
cacheModelsEnabled="true"
/>
<typeHandler javaType="java.util.Date" callback="xxxxxxxxx.CustomDateTypeHandler" />
<sqlMap resource="sqlmap/sqlmap-price.xml" />
</sqlMapConfig>
这里需要注意的是
1. typeHandler 中的 jdbcType 取值应为 null, DATE, TIME, 这里用的null
2. typehandler 必须要在 sqlmap 前面, 否则sqlmap中的类型handler就会用默认的
下面是自定义的datetypehandler
package xxxxxxxxx;
import java.sql.CallableStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import com.ibatis.sqlmap.engine.type.DateTypeHandler;
public class CustomDateTypeHandler extends DateTypeHandler {
@Override
public Object getResult(ResultSet rs, String columnName) throws SQLException {
try {
return super.getResult(rs, columnName);
} catch(SQLException e) {
if("S1009".equals(e.getSQLState())) {
return null;
}
throw e;
}
}
@Override
public Object getResult(ResultSet rs, int columnIndex) throws SQLException {
try {
return super.getResult(rs, columnIndex);
} catch(SQLException e) {
if("S1009".equals(e.getSQLState())) {
return null;
}
throw e;
}
}
@Override
public Object getResult(CallableStatement cs, int columnIndex) throws SQLException {
try {
return super.getResult(cs, columnIndex);
} catch(SQLException e) {
if("S1009".equals(e.getSQLState())) {
return null;
}
throw e;
}
}
}
