Maven Web项目配置Mybatis

一、添加Mybatis和数据库相关的包

1 pom.xml中添加的包有mybatis，mybatis-spring，druid，MySQL-connector-Java，commons-io，reflectasm

完整的pom.xml内容为

1. <project xmlns="http://maven.apache.org/POM/4.0.0"
2. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2 /src/main/webapp/WEB-INF/lib/中添加cglib-3.1.jar

二、配置web.xml

1. <?xml version="1.0" encoding="UTF-8"?>

4. <!--
5. plugins在配置文件中的位置必须符合要求，否则会报错，顺序如下:
6. properties?, settings?,
7. typeAliases?, typeHandlers?,
8. objectFactory?,objectWrapperFactory?,
9. plugins?,
10. environments?, databaseIdProvider?, mappers?
11. -->
12. <configuration>
13. <properties>
14. </properties>
15. <!-- mybatis的内部配置 -->
16. <settings>
17. <!--使全局的映射器启用缓存  -->
18. <setting name="cacheEnabled" value="true" />
19. <!--启用延迟加载 ,当禁用时，所有关联对象都会即时加载 -->
20. <setting name="lazyLoadingEnabled" value="false" />
21. <!-- 当启用时，有延迟加载属性的对象在被调用时将会完全加载任意属性。否则，每种属性将会按需要加载  -->

27. <!--不能用生成键  -->
28. <setting name="useGeneratedKeys" value="false" />

30. <setting name="autoMappingBehavior" value="PARTIAL" />
31. <!--默认执行器为SIMPLE,SIMPLE执行器没有什么特别之处。REUSE执行器重用预处理语句。BATCH执行器重用语句和批量更新   -->
32. <setting name="defaultExecutorType" value="SIMPLE" />
33. <!--超时时间2500毫妙,它决定驱动等待一个数据库响应的时间  -->
34. <setting name="defaultStatementTimeout" value="25000" />
