3 ways to add plugins to MyBatis

1 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>
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <property name="helperDialect" value="mysql" />
        </plugin>
    </plugins>
</configuration>


2,spring-application.xml

  <!-- 配置 mybatis -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation"  value="classpath:mybatis/mybatis-config.xml" />
<property name="mapperLocations">
<list>
<value>classpath:com/*Mapper.xml</value>
</list>
</property>
<!-- 可以在此配置MyBatis分页插件 -->
<!--  -->
        <property name="plugins">
            <array>
                <bean class="com.github.pagehelper.PageInterceptor">
                    <property name="properties">
                        <value>helperDialect=mysql</value>
                    </property>
                </bean>
            </array>
        </property>       
</bean>


3 MybatisConfig.java

  @Configuration
public class MybatisConfig {
    @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {
        SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
        sqlSessionFactory.setDataSource(dataSource());
        sqlSessionFactory.setFailFast(true);
        // 分页插件
        PageHelper pageHelper = new PageHelper();
        Properties properties = new Properties();
        properties.setProperty("dialect", "mysql");
        properties.setProperty("offsetAsPageNum", "true");
        properties.setProperty("rowBoundsWithCount", "true");
        properties.setProperty("pageSizeZero", "true");
        properties.setProperty("reasonable", "true");
        pageHelper.setProperties(properties);
        // 添加插件
        sqlSessionFactory.setPlugins(new Interceptor[]{pageHelper});
        return sqlSessionFactory.getObject();
    }

    @Bean
    public DataSourceTransactionManager transactionManager() {
        return new DataSourceTransactionManager(dataSource());
    }

    @PostConstruct
    public void postConstruct() {
    }
}
