错误：org.springframework.web.context.ContextLoader-上下文初始化失败org.springframework.beans.factory.BeanCreationException

Question

I am developing web-site(spring 3.1.1) in tomcat 7 but it is giving error

 ERROR: org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [config/applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [config/SqlMapConfig.xml]; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration.

I tried to solve this error many times but it failed. How can I solve this error? I need your help.

here are my SqlMapConfig.xml,applicationContext and my root-context.

my SqlMapConfig.xml(config/SqlMapConfig.xml)

 <?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"> <mapper namespace="BoardDao"> <select id="selectList" parameterType="map" resultType="BoardCommand"> SELECT seq, writer, title, content, pwd, hit, regdate, filename FROM ( SELECT a.*, rownum rnum FROM ( SELECT * FROM springboardtest <where> <if test ="keyWord != '' and keyField =='title'"> title like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='writer'"> writer like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='content'"> content like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='all'"> content like '%' ||#{keyWord}||'%' or title like '%' ||#{keyWord}||'%' or writer like '%' ||#{keyWord}||'%' </if> </where> ORDER BY seq desc)a) <![CDATA[ WHERE rnum >= #{start} AND rnum <= #{end} ]]> </select> <select id="selectCount" parameterType="map" resultType="Integer"> SELECT count(*) FROM springboardtest <where> <if test ="keyWord != '' and keyField =='title'"> title like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='writer'"> writer like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='content'"> content like '%' ||#{keyWord}||'%' </if> <if test ="keyWord != '' and keyField =='all'"> content like '%' ||#{keyWord}||'%' or title like '%' ||#{keyWord}||'%' or writer like '%' ||#{keyWord}||'%' </if> </where> </select> </mapper> 

my applicationContext(config/applicationContext)

and my root-context

Answer 1

Configuration is configuration, try to find it out from google. It looks something like below

<configuration>
<settings>
    <setting name="cacheEnabled"                value="true" />
    <setting name="multipleResultSetsEnabled"   value="true" />
    <setting name="useColumnLabel"              value="true" />
    <setting name="useGeneratedKeys"            value="false" />
    <setting name="defaultExecutorType"         value="SIMPLE" />
    <setting name="defaultStatementTimeout"     value="25000" />
    <setting name="jdbcTypeForNull"             value="NULL" />
</settings>

<typeAliases>
</typeAliases>

</configuration>

And check your sqlSessionFactory bean configuration again

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       <property name="dataSource" ref="dataSource" />
       <property name="configLocation" value="classpath:/configuration/mybatis-config.xml"/>
       <property name="mapperLocations" value="classpath*:sample/config/mappers/**/*.xml" />
</bean>

I think, that's why fail to build.

Answer 2

As jamesBlake rightly mentioned, configuration file is configuration. You are providing the mapper file as configuration and ibatis cannot parse it as configuration.

Configuration is file where you define your ibatis settings and alias (if any) which can be used in mapper files

Mapper file is one where you actually write your queries.You can have as many mapper files as you want.
