我正在命令行运行器和Web应用程序上进行spring boot。这两个应用程序都需要用oracle钱包来实现,所以我实现了oracle钱包。命令行运行器能够使用oracle数据源使用spring jdbc模板连接到数据库,但是相同的配置无法为数据源对象创建bean。当使用数据库用户名和密码实现相同时,我能够连接。
我正在接受这篇文章的帮助 - [Connect to Oracle DB from Spring-jdbc with Oracle Wallet authentification
代码类似于
System.setProperty("oracle.net.tns_admin", "path/to/your/tnsnames");
OracleDataSource ds = new OracleDataSource();
Properties props = new Properties();
props.put("oracle.net.wallet_location", "(source=(method=file)(method_data=(directory=path/to/your/wallet)))");
ds.setConnectionProperties( props );
ds.setURL("jdbc:oracle:thin:/@dbAlias"); //dbAlias should match what's in your tnsnames
return ds;
我从启动应用程序的application.properties设置了所有属性,并且在创建数据源时出现空指针异常。
非常感谢在这方面的任何指针或帮助。

尝试之后,当我们需要在春季启动中加入oracle钱包时,我可以弄清楚我们需要做什么。
1. In application.properties put two properties,
A> spring.datasource.url=jdbc:oracle:thin:/@<DB_ALIAS_NAME>
B> spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
2. On boot runner/configuration class,
A> Define the dataSource bean like this,
@Bean
public DataSource dataSource() {
OracleDataSource dataSource = null;
try {
dataSource = new OracleDataSource();
Properties props = new Properties();
String oracle_net_wallet_location =
System.getProperty("oracle.net.wallet_location");
props.put("oracle.net.wallet_location", "(source=(method=file)(method_data=(directory="+oracle_net_wallet_location+")))");
dataSource.setConnectionProperties(props);
dataSource.setURL(url);
} catch(Exception e) {
e.printStackTrace();
}
return dataSource;
}
B> Define the jdbcTemplate bean as follows,
@Bean
public JdbcTemplate jdbcTemplate(DataSource dataSource) {
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource());
jdbcTemplate.setFetchSize(20000);
return jdbcTemplate;
}
3. Now we need to set jvm arguments in boot runner class like as follows,
-Doracle.net.wallet_location=<PATH_TO_WALLET_DIR> -Doracle.net.tns_admin=<PATH_TO_WALLET_DIR>
Note - <WALLET_DIR> should contain .sso, .p12 and .ora files. On external
server like tomcat, set above two variables on catalina.sh or catalina.bat
depending on your environment OS.
I hope this helps.
Thanks,
