在不使用JNDI的情況下配置Tomcat連接池

Question

我是連接池技術的新手，在Tomcat的JDBC連接池官方指南中，有一個選項可以通過初始化Data Source類來初始化Plain Java Class的池。但是當我嘗試實施相同的時候，它總是給我以下的例外。我的網址是正確的。

SEVERE: Unable to create initial connections of pool. 
java.sql.SQLException: invalid arguments in call 
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134) 

有人能幫助理解使用池屬性設置連接池所需的全部內容嗎？

String dburl="jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)(ADDRESS=(PROTOCOL=TCP)(HOST=hostname) (PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=shostname2)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=Service)))"; 

p.setUrl(dburl); 
p.setDriverClassName("oracle.jdbc.OracleDriver"); 
p.setUsername(username); 
p.setPassword(pwd); 
p.setJmxEnabled(true); 
p.setTestWhileIdle(false); 
p.setTestOnBorrow(true); 
p.setValidationQuery("SELECT 1 from dual"); 
p.setTestOnReturn(false); 
p.setValidationInterval(30000); 
p.setTimeBetweenEvictionRunsMillis(30000); 
p.setMaxActive(100); 
p.setInitialSize(10); 
p.setMaxWait(10000); 
p.setRemoveAbandonedTimeout(600); 
p.setMinEvictableIdleTimeMillis(30000); 
p.setMinIdle(10); 
p.setLogAbandoned(true); 

p.setRemoveAbandoned(true); 
p.setJdbcInterceptors(
     "org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;" 
     + "org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer;" 
     + "org.apache.tomcat.jdbc.pool.interceptor.ResetAbandonedTimer"); 

p.setLogValidationErrors(true); datasource = new org.apache.tomcat.jdbc.pool.DataSource(); 
datasource.setPoolProperties(p);

Answer 1

發生因oracle.jdbc驅動程序這個問題，你可以代替p.setDriverClassName("oracle.jdbc.OracleDriver");
