Question

在Spring Restful API中使用jooq和HikariCP DataSource（Autowired）时，我遇到了问题，jooq在某种程度上不会释放DataSource。

一些代码：

@Autowired
private DataSource dataSource;
//Further down 
DSLContext create = DSL.using(dataSource, SQLDialect.MYSQL);

使用此存储库/调用两到三次后，我打开了太多连接。

我的dispatcher-servlet.xml：

好的，我修复了问题：

    @Autowired
private DataSource dataSource;
//Further down 
Connection con=dataSource.getConnection();
DSLContext create = DSL.using(con, SQLDialect.MYSQL);
//Execute code here
con.close();

因此，我没有直接使用DataSource，而是使用了连接并将其释放。

HikariCP与jooq的连接太多了
