插件扩展

分页插件 ： com.baomidou.mybatisplus.plugins.PaginationInterceptor 执行分析插件： com.baomidou.mybatisplus.plugins.SqlExplainInterceptor 性能分析插件： com.baomidou.mybatisplus.plugins.PerformanceInterceptor 乐观锁插件: com.baomidou.mybatisplus.plugins.OptimisticLockerInterceptor

<!--整合Mybatis-Plus配置-->
<bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean">
    <property name="configLocation" value="classpath:mybatis-config.xml" />
    <property name="dataSource" ref="dataSource" />
    <property name="mapperLocations" value="classpath:/mappers/*.xml" />
    <!-- Mybatis Plus全局配置 -->
    <property name="globalConfig" ref="globalConfig"></property>
    <!-- Mybatis Plus插件配置 -->
    <property name="plugins">
        <array>
            <!-- 分页插件配置 -->
            <bean id="paginationInterceptor"
                  class="com.baomidou.mybatisplus.plugins.PaginationInterceptor"/>
            <!-- 执行分析配置 -->
            <bean id="sqlExplainInterceptor"
                  class="com.baomidou.mybatisplus.plugins.SqlExplainInterceptor">
                <property name="stopProceed" value="true" />
            </bean>
            <!-- 乐观锁插件 -->
            <bean id="optimisticLockerInterceptor"
                  class="com.baomidou.mybatisplus.plugins.OptimisticLockerInterceptor">
            </bean>
            <!-- 性能拦截器，兼打印sql，不建议生产环境配置-->
            <bean id="performanceInterceptor"
                  class="com.baomidou.mybatisplus.plugins.PerformanceInterceptor">
                <property name="format" value="true" />
                <!--<property name="maxTime" value="5" />-->
            </bean>
        </array>
    </property>
</bean>

Mybatis-Plus逻辑删除配置

<bean id="globalConfig" class="com.baomidou.mybatisplus.entity.GlobalConfiguration">
    <property name="sqlInjector" ref="logicSqlInjector" />
    <property name="logicDeleteValue" value="-1" />
    <property name="logicNotDeleteValue" value="1" />
    <property name="idType" value="2" />
</bean>
<bean id="logicSqlInjector" class="com.baomidou.mybatisplus.mapper.LogicSqlInjector" />

逻辑删除实体

@TableName("tbl_user")
public class UserLogicDelete {

    private Long id;
    ...
    @TableField(value = "delete_flag")
    @TableLogic
    private Integer deleteFlag;
}
