Mybatis || Mybatis-Plus中configuration和configLocation无法同时使用记录

Mybatis || Mybatis-Plus中configuration和configLocation无法同时使用记录

1. 当在SpringBoot项目中配置的yml中对于mybatis || mp的参数同时配置了configuration和configLocation的情况下会导致的问题如下

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is java.lang.IllegalStateException: Property 'configuration' and 'configLocation' can not specified with together

解析原因是因为框架就是不允许这个样子, 因为mp是mybatis的加强, 所以也会出现同样的问题

2. 具体代码如下

• mybatis的代码是SqlSessionFactoryBean类中的

  @Override
  public void afterPropertiesSet() throws Exception {
        
        
      notNull(dataSource, "Property 'dataSource' is required");
      notNull(sqlSessionFactoryBuilder, "Property 'sqlSessionFactoryBuilder' is required");
      state((configuration == null && configLocation == null) || !(configuration != null && configLocation != null),
            "Property 'configuration' and 'configLocation' can not specified with together");
  
      this.sqlSessionFactory = buildSqlSessionFactory();
  }
  

• mybatis的代码是MybatisSqlSessionFactoryBean类中

  @Override
  public void afterPropertiesSet() throws Exception {
        
        
      notNull(dataSource, "Property 'dataSource' is required");
      state((configuration == null && configLocation == null) || !(configuration != null && configLocation != null),
            "Property 'configuration' and 'configLocation' can not specified with together");
      //TODO 清理掉资源  建议不要保留这个玩意了
      SqlRunner.DEFAULT.close();
      this.sqlSessionFactory = buildSqlSessionFactory();
  }
  

具体还是使用yml优雅一点,可能没人会两个都用
