这次分析mybatis的xml文件
1.
<?xml version="1.0" encoding="UTF-8" ?>
<configuration xmlns="http://mybatis.org/schema/mybatis-config"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://mybatis.org/schema/mybatis-config http://mybatis.org/schema/mybatis-config.xsd">
xml编写...
</configuration>
2.资源配置
<!--方法一： 从外部指定properties配置文件, 除了使用resource属性指定外，还可通过url属性指定url-->
<!--方法二. 直接用name，value设置 -->
<properties resource="org/apache/ibatis/builder/jdbc.properties">
<property name="prop1" value="aaaa"/>
<property name="jdbcTypeForNull" value="NULL" />
</properties>
3.setting 标签
代码：
<settings>
<setting name="autoMappingBehavior" value="NONE"/>
<setting name="autoMappingUnknownColumnBehavior" value="WARNING"/>
<setting name="cacheEnabled" value="false"/>
<setting name="proxyFactory" value="CGLIB"/>
<setting name="lazyLoadingEnabled" value="true"/>
<setting name="aggressiveLazyLoading" value="true"/>
<setting name="multipleResultSetsEnabled" value="false"/>
<setting name="useColumnLabel" value="false"/>
<setting name="useGeneratedKeys" value="true"/>
<setting name="defaultExecutorType" value="BATCH"/>
<setting name="defaultStatementTimeout" value="10"/>
<setting name="defaultFetchSize" value="100"/>
<setting name="mapUnderscoreToCamelCase" value="true"/>
<setting name="safeRowBoundsEnabled" value="true"/>
<setting name="localCacheScope" value="STATEMENT"/>
<setting name="jdbcTypeForNull" value="${jdbcTypeForNull}"/>
<setting name="lazyLoadTriggerMethods" value="equals,clone,hashCode,toString,xxx"/>
<setting name="safeResultHandlerEnabled" value="false"/>
<setting name="defaultScriptingLanguage" value="org.apache.ibatis.scripting.defaults.RawLanguageDriver"/>
<setting name="callSettersOnNulls" value="true"/>
<setting name="logPrefix" value="mybatis_"/>
<setting name="logImpl" value="SLF4J"/>
<setting name="vfsImpl" value="org.apache.ibatis.io.JBoss6VFS"/>
<setting name="configurationFactory" value="java.lang.String"/>
</settings>
4. typeAliases是用来设置类路径别名的
<typeAliases>
<typeAlias alias="User" type="com.majing.learning.mybatis.entity.User"/>
</typeAliases>
