spring boot mybatis 配置整理
import java.io.IOException;
import java.util.Properties;
import javax.sql.DataSource;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.ibatis.plugin.Interceptor;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.DefaultResourceLoader;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
import com.github.pagehelper.PageHelper;
@Configuration
@EnableTransactionManagement
public class MybatisConfiguration implements TransactionManagementConfigurer{
private static Log logger = LogFactory.getLog(MybatisConfiguration.class);
@Autowired
private DataSource dataSource;
// 提供SqlSeesion
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactoryBean() {
try {
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource);
// 手写配置
// 配置类型别名
sessionFactoryBean.setTypeAliasesPackage("com.zsx.entity");
// 配置mapper的扫描，找到所有的mapper.xml映射文件
Resource[] resources = new PathMatchingResourcePatternResolver()
.getResources("classpath:mybatis/mapper/*.xml");
sessionFactoryBean.setMapperLocations(resources);
// 加载全局的配置文件
sessionFactoryBean.setConfigLocation(
new DefaultResourceLoader().getResource("classpath:mybatis/mybatis-config.xml"));
//添加插件
sessionFactoryBean.setPlugins(new Interceptor[]{pageHelper()});
return sessionFactoryBean.getObject();
} catch (IOException e) {
logger.warn("mybatis resolver mapper*xml is error");
return null;
} catch (Exception e) {
logger.warn("mybatis sqlSessionFactoryBean create error");
return null;
}
}
@Bean
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
@Bean
public PageHelper pageHelper(){
logger.info("MyBatis分页插件PageHelper");
//分页插件
PageHelper pageHelper = new PageHelper();
Properties properties = new Properties();
properties.setProperty("offsetAsPageNum", "true");
properties.setProperty("rowBoundsWithCount", "true");
properties.setProperty("reasonable", "true");
properties.setProperty("supportMethodsArguments", "true");
properties.setProperty("returnPageInfo", "check");
properties.setProperty("params", "count=countSql");
pageHelper.setProperties(properties);
return pageHelper;
}
}先在配置文件application.yml中添加
# MyBatis
mybatis:
# 配置类型别名
typeAliasesPackage: com.zsx.entity
# 配置mapper的扫描，找到所有的mapper.xml映射文件
mapperLocations: classpath:mybatis/mapper/*.xml
# 加载全局的配置文件
configLocation: classpath:mybatis/mybatis-config.xml
然后配置文件为：
import java.io.IOException;
import javax.sql.DataSource;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.DefaultResourceLoader;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
@Configuration
@EnableTransactionManagement
public class MybatisConfiguration implements TransactionManagementConfigurer{
private static Log logger = LogFactory.getLog(MybatisConfiguration.class);
// 配置类型别名
@Value("${mybatis.typeAliasesPackage}")
private String typeAliasesPackage;
// 配置mapper的扫描，找到所有的mapper.xml映射文件
@Value("${mybatis.mapperLocations}")
private String mapperLocations;
// 加载全局的配置文件
@Value("${mybatis.configLocation}")
private String configLocation;
@Autowired
private DataSource dataSource;
// DataSource配置
// @Bean
// @ConfigurationProperties(prefix = "spring.datasource")
// public DruidDataSource dataSource() {
// return new com.alibaba.druid.pool.DruidDataSource();
// }
// 提供SqlSeesion
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactoryBean() {
try {
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource);
// 读取配置
sessionFactoryBean.setTypeAliasesPackage(typeAliasesPackage);
//
Resource[] resources = new PathMatchingResourcePatternResolver()
.getResources(mapperLocations);
sessionFactoryBean.setMapperLocations(resources);
// //
sessionFactoryBean.setConfigLocation(
new DefaultResourceLoader().getResource(configLocation));
//添加插件 （改为使用配置文件加载了）
// sqlSessionFactoryBean.setPlugins(new Interceptor[]{pageHelper()});
return sessionFactoryBean.getObject();
} catch (IOException e) {
logger.warn("mybatis resolver mapper*xml is error");
return null;
} catch (Exception e) {
logger.warn("mybatis sqlSessionFactoryBean create error");
return null;
}
}
// @Bean
// public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
// return new SqlSessionTemplate(sqlSessionFactory);
// }
// @Bean
// public PlatformTransactionManager transactionManager(){
// return new DataSourceTransactionManager(dataSource);
// }
@Bean
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
}
最后还有配置一个扫描mapper的类：
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
//TODO 注意，由于MapperScannerConfigurer执行的比较早，所以必须有下面的注解
@AutoConfigureAfter({MybatisConfiguration.class})
public class MyBatisMapperScannerConfig {
@Bean
public MapperScannerConfigurer mapperScannerConfigurer(){
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
mapperScannerConfigurer.setBasePackage("com.zsx.dao");
return mapperScannerConfigurer;
}
}
还有一个 mybatis-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<properties>
<property name="dialect" value="mysql" />
</properties>
<settings>
<!-- 开启驼峰匹配 -->
<setting name="mapUnderscoreToCamelCase" value="true"/>
<!-- 这个配置使全局的映射器启用或禁用缓存。系统默认值是true，设置只是为了展示出来 -->
<setting name="cacheEnabled" value="true" />
<!-- 全局启用或禁用延迟加载。当禁用时，所有关联对象都会即时加载。 系统默认值是true，设置只是为了展示出来 -->
<setting name="lazyLoadingEnabled" value="true" />
<!-- 允许或不允许多种结果集从一个单独的语句中返回（需要适合的驱动）。 系统默认值是true，设置只是为了展示出来 -->
<setting name="multipleResultSetsEnabled" value="true" />
<!--使用列标签代替列名。不同的驱动在这方便表现不同。参考驱动文档或充分测试两种方法来决定所使用的驱动。 系统默认值是true，设置只是为了展示出来 -->
<setting name="useColumnLabel" value="true" />
<!--允许 JDBC 支持生成的键。需要适合的驱动。如果设置为 true 则这个设置强制生成的键被使用，尽管一些驱动拒绝兼容但仍然有效（比如
Derby）。 系统默认值是false，设置只是为了展示出来 -->
<setting name="useGeneratedKeys" value="false" />
<!--配置默认的执行器。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 系统默认值是SIMPLE，设置只是为了展示出来 -->
<setting name="defaultExecutorType" value="SIMPLE" />
<!--设置超时时间，它决定驱动等待一个数据库响应的时间。 系统默认值是null，设置只是为了展示出来 -->
<setting name="defaultStatementTimeout" value="25000" />
</settings>
<!-- 分页助手 -->
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<!-- 数据库方言 -->
<property name="dialect" value="mysql" />
<property name="offsetAsPageNum" value="true" />
<!-- 设置为true时，使用RowBounds分页会进行count查询 会去查询出总数 -->
<property name="rowBoundsWithCount" value="true" />
<property name="pageSizeZero" value="true" />
<property name="reasonable" value="true" />
</plugin>
</plugins>
</configuration>
