sql xml define
When I use Mybatis LongTypeHandler in resultMap, I got error bellow, I don't know why. Does anyone could help on this?
Thanks in advance.
<resultMap id="detail_siteTypeConfig" type="java.util.HashMap">
<result typeHandler="org.apache.ibatis.type.LongTypeHandler" javaType="java.lang.Long" property="siteID" column="siteid"/>
<result typeHandler="org.apache.ibatis.type.LongTypeHandler" javaType="java.lang.Long" property="siteType" column="sitetype"/>
<result typeHandler="com.webex.webapp.common.util.mybatis.StringEmptyTypeHandler" javaType="java.lang.String" property="itemName" column="itemname"/>
<result typeHandler="com.webex.webapp.common.util.mybatis.StringEmptyTypeHandler" javaType="java.lang.String" property="itemValue" column="itemvalue"/>
</resultMap>
<select id="xxxxxx" resultMap="detail_siteTypeConfig">
select siteid, sitetype, itemname, itemvalue from tablexxxx where siteid=#{siteId} and sitetype=#{siteType}
</select>

This is my project demo, I want to use MyBatis xml configuration. But I got a SAXParseException error, like this

this is my mapper xml file:
<?xml version="1.0" encoding="UTF-8" ?>
<mapper namespace="com.ryanqy.mapper.UserMapper" xmlns="http://mybatis.org/schema/mybatis-mapper">
<resultMap id="userResultMap" type="com.ryanqy.entity.UserEntity">
<result column="username" property="username"/>
<result column="password" property="password"/>
</resultMap>
<select id="findUserByUserName" resultMap="userResultMap">
select * from uuc_user where username = #{userName}
</select>
</mapper>
Problem is with your mybatis config:
mybatis:
configuration:
map-underscore-to-camel-case: true
type-aliases-package: com.ryanqy.entity
mapper-locations: mapper
change mapper-locations to:
mapper-locations: mapper/UserMapper.xml
#OR
mapper-locations: mapper/*.xml
If you change, you receive error with missing DOCTYPE in your mapper XML, so add something like this
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
While trying to convert my app from using MyBatis [it was iBatis before], I've been getting the following error, in spite of trying to make so many different kinds of changes to the code: What am I doing wrong? Any help would be really really really great!!!

Java code:
try {
List < Report > reports = super.getSqlSession().selectList("retrieveReports");
if(log.isDebugEnabled()){
log.debug("Retrieved " + reports.size() + " reports, in method: retrieveReports()");
}
return reports;
// Attempt to catch different kinds of exceptions.
} catch (Exception e) {
throw new RuntimeException("Exception caught while trying to retrieve reports", e);
}
You have to specify a parameterType in the select statement, either map or custom class. An instance has to be passed on statement invocation.
resultType is not used, then irrelevant.
Procedure actually writes in a field of the "input" parameter passed to mybatis statement, and the statement does not return anything.
Mapper interface would be: void retrieveReports(Map<String, Object> params);
And your call:
Map<String, Object> params = new HashMap<String, Object>();
session.selectList("retrieveReports", params);
List<Report> reports = (List<Report>)params.get("reports");
Param may also be a custom type with property private List<Report> reports;.
My mapper interface looks like this.
public interface CommonMapper {
long selectSequenceNumber(String sequenceName);
}
And I prepared sql mapper looks like this.
<sql id="sequenceNumber">
<choose>
<when test="_databaseId == 'derby'">
VALUES NEXT VALUE FOR #{sequenceName}
</when>
<otherwise>
SELECT #{sequenceName}.NEXTVAL FROM DUAL
</otherwise>
</choose>
</sql>
<select id="selectSequenceNumber" resultType="_long">
<!--<include refid="....mapper.CommonMapper.sequenceNumber"/>-->
<include refid="sequenceNumber"/>
</select>
When I test mapper #{sequenceName} part is not substituted with given.
14:36:09.492 [main] DEBUG ....selectSequenceNumber - ==> Preparing: VALUES NEXT VALUE FOR ?
14:36:09.724 [main] ERROR ....PersistenceTests - failed to apply function for SqlSession
org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: java.sql.SQLSyntaxErrorException: Syntax error: Encountered "?" at line 1, column 23.
### The error may exist in .../CommonMapper.xml
### The error may involve ....CommonMapper.selectSequenceNumber
### The error occurred while executing a query
### SQL: VALUES NEXT VALUE FOR ?
### Cause: java.sql.SQLSyntaxErrorException: Syntax error: Encountered "?" at line 1, column 23.
Is this normal? How can I fix this?
You need to use string substitution ${sequenceName} instead of setting the parameter with #{} for direct string placement in your queries (such as for giving object names, dynamic sql etc...)
<sql id="sequenceNumber">
<choose>
<when test="_databaseId == 'derby'">
VALUES NEXT VALUE FOR ${sequenceName}
</when>
<otherwise>
SELECT ${sequenceName}.NEXTVAL FROM DUAL
</otherwise>
</choose>
</sql>
<select id="selectSequenceNumber" resultType="_long">
<!--<include refid="....mapper.CommonMapper.sequenceNumber"/>-->
<include refid="sequenceNumber"/>
</select>
I don't know what is wrong.
Something is bad with mapper but everything looks good.
File UserMapper.xml

You can use following doc type. However I find some discrepancy in the code you have copied. Are you sure of INSERT and SELECT statements. I hope its copy mistake
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<select id="getUser" parameterType="int" resultType="com.javacodegeeks.snippets.enterprise.User">

I am performing a transformation and getting the following error:

There is a link to a similar problem here, 109 Error, but i don't think this has to do with my endpoint.
I'm guessing a 109 is a bush-league error, so nay help is appreciated.
The source of my issue was that I had a data mismatch in my get/set methods and after having written a lot of PHP over the last year, I over looked that.
