如何重新使用Cloud Foundry中的连接； MySQL睡眠连接未使用

Question

基于上述配置

PoolConfig poolConfig = new PoolConfig(10, 20, 3000);

ConnectionConfig connectionConfig = new ConnectionConfig("useUnicode=yes;characterEncoding=utf8;");

DataSourceConfig dbConfig = new DataSourceConfig(poolConfig, connectionConfig);

PoolConfig poolConfig = new PoolConfig(10, 20, 3000);

ConnectionConfig connectionConfig = new ConnectionConfig("useUnicode=yes;characterEncoding=utf8;");

return connectionFactory().dataSource("databaseName", dbConfig);

1）jdbc模板连接没有关闭，连接也没有返回到池中。

2）当我在Mysql中说“显示进程列表”都是睡眠连接时，它没有重用连接池，也没有重新建立连接池。

PoolConfig poolConfig = new PoolConfig(10, 20, 3000);

ConnectionConfig connectionConfig = new ConnectionConfig("useUnicode=yes;characterEncoding=utf8;");

DataSourceConfig dbConfig = new DataSourceConfig(poolConfig, connectionConfig);

PoolConfig poolConfig = new PoolConfig(10, 20, 3000);

ConnectionConfig connectionConfig = new ConnectionConfig("useUnicode=yes;characterEncoding=utf8;");

return connectionFactory().dataSource("databaseName", dbConfig);
