Java Weblogic数据源连接
我试图通过Java客户端访问数据源连接，代码如下：Java Weblogic数据源连接,java,database,oracle11g,weblogic,datasource,Java,Database,Oracle11g,Weblogic,Datasource,我试图通过Java客户端访问数据源连接，代码如下： Connection conn; Statement stmt; ResultSet rs; try { Properties prop = new Properties(); prop.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); prop.put(javax.naming.Context.PROVIDE
Connection conn;
Statement stmt;
ResultSet rs;
try {
Properties prop = new Properties();
prop.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
prop.put(javax.naming.Context.PROVIDER_URL, "t3://localhost:7001");
Context ctx = new InitialContext(prop);
Object obj = ctx.lookup("test/datasource");
System.out.println("Data Source Found….");
DataSource ds = (DataSource) obj;
conn = ds.getConnection();
System.out.println("Data Source User Name::"+conn.getMetaData().getUserName());
stmt = conn.createStatement();
String query = "select 1 from dual";
System.out.println("Query " + query);
rs = stmt.executeQuery(query);
if (rs != null) {
System.out.println("Some Data Found in Query");
} else {
System.out.println("No Data Found in Query");
}
ctx.close();
} catch (Exception e) {
e.printStackTrace();
}
//Some Code
weblogic.jndi.Environment env = new weblogic.jndi.Environment();
env.setInitialContextFactory(Environment.DEFAULT_INITIAL_CONTEXT_FACTORY);
env.setProviderUrl("t3://${weblogic_host_ip}:${weblogic_port_number}");
env.setSecurityPrincipal(${DB_USER});
env.setSecurityCredentials(${DB_PASSWORD});
java.lang.Object obj = null;
try {
javax.naming.Context ctx = env.getInitialContext();
obj = ctx.lookup(${JNDI_NAME_OF_DATA_SOURCE});
javax.sql.DataSource ds = (javax.sql.DataSource) obj;
java.sql.Connection conn = ds.getConnection();
java.sql.Statement stmt = conn.createStatement();
java.sql.ResultSet rs = stmt.executeQuery("select '5' from dual");
if(rs != null){
rs.next();
System.out.println(rs.getString(1));
}
} catch (javax.naming.NamingException e) {
e.printStackTrace();
}
//Other Code ....
提前感谢。如果您使用的是Weblogic 10.3及以上版本，最好的傻瓜解决方案（不会让您抓狂）是： 只包括在中找到的wlfullclient.jar ${wlserver\U 10.3\U安装\U home}\server\lib文件夹 在您的类路径（lib）中。这样您就不需要weblogic.jar了 如果找不到wlfullclient.jar，则构建它。以下是您如何构建它： 然后编写以下代码：
Connection conn;
Statement stmt;
ResultSet rs;
try {
Properties prop = new Properties();
prop.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
prop.put(javax.naming.Context.PROVIDER_URL, "t3://localhost:7001");
Context ctx = new InitialContext(prop);
Object obj = ctx.lookup("test/datasource");
System.out.println("Data Source Found….");
DataSource ds = (DataSource) obj;
conn = ds.getConnection();
System.out.println("Data Source User Name::"+conn.getMetaData().getUserName());
stmt = conn.createStatement();
String query = "select 1 from dual";
System.out.println("Query " + query);
rs = stmt.executeQuery(query);
if (rs != null) {
System.out.println("Some Data Found in Query");
} else {
System.out.println("No Data Found in Query");
}
ctx.close();
} catch (Exception e) {
e.printStackTrace();
}
//Some Code
weblogic.jndi.Environment env = new weblogic.jndi.Environment();
env.setInitialContextFactory(Environment.DEFAULT_INITIAL_CONTEXT_FACTORY);
env.setProviderUrl("t3://${weblogic_host_ip}:${weblogic_port_number}");
env.setSecurityPrincipal(${DB_USER});
env.setSecurityCredentials(${DB_PASSWORD});
java.lang.Object obj = null;
try {
javax.naming.Context ctx = env.getInitialContext();
obj = ctx.lookup(${JNDI_NAME_OF_DATA_SOURCE});
javax.sql.DataSource ds = (javax.sql.DataSource) obj;
java.sql.Connection conn = ds.getConnection();
java.sql.Statement stmt = conn.createStatement();
java.sql.ResultSet rs = stmt.executeQuery("select '5' from dual");
if(rs != null){
rs.next();
System.out.println(rs.getString(1));
}
} catch (javax.naming.NamingException e) {
e.printStackTrace();
}
//Other Code ....
您是否已打开WebLogic控制台并验证您的数据源是否一切正常？它是否可以从web控制台进行测试？是否显示在sysout中<代码>System.out.println（“找到数据源…”）
