spring boot项目自定义数据源，mybatisplus分页、逻辑删除无效解决方法

Spring Boot项目中数据源的配置可以通过两种方式实现：

1.application.yml或者application.properties配置

2.注入DataSource及SqlSessionFactory两个Bean

通过第二种方式配置数据源则按照MybatisPlus官方文档使用分页及逻辑删除插件会无效，解决思路是在初始化SqlSessionFactory将插件设置进去

/**
 * 逻辑删除插件
 */
@Bean
public GlobalConfig globalConfig() {
    GlobalConfig globalConfig = new GlobalConfig();
    GlobalConfig.DbConfig dbConfig = new GlobalConfig.DbConfig();
    dbConfig.setLogicDeleteValue("Y");
    dbConfig.setLogicNotDeleteValue("N");
    globalConfig.setDbConfig(dbConfig);
    globalConfig.setSqlInjector(new LogicSqlInjector());
    return globalConfig;
}

/**
 * 分页插件
 */
@Bean
public PaginationInterceptor paginationInterceptor() {
    PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
    paginationInterceptor.setDialectType(DbType.MYSQL.getDb());
    return paginationInterceptor;
}

@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactory() throws Exception {
    logger.info("初始化SqlSessionFactory");
    String mapperLocations = "classpath:mybatis/mapper/**/*.xml";
    String configLocation = "classpath:mybatis/mybatis-config.xml";
    MybatisSqlSessionFactoryBean sqlSessionFactory = new MybatisSqlSessionFactoryBean();
    sqlSessionFactory.setDataSource(dataSource()); //数据源
    ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
    sqlSessionFactory.setMapperLocations(resolver.getResources(mapperLocations));
    sqlSessionFactory.setConfigLocation(resolver.getResource(configLocation));
    sqlSessionFactory.setTypeAliasesPackage("com.innjoy.pms.order.infrastructure.domain.model");
    sqlSessionFactory.setGlobalConfig(globalConfig());
    sqlSessionFactory.setPlugins(new Interceptor[]{paginationInterceptor()});
    return sqlSessionFactory.getObject();
}
