DataSource為null-在OpenShift JBOSS AS 7上部署

Question

我用冬眠和春季開發了一個項目。 我對所有注釋都使用。 我正在嘗試在JBOSS AS 7中的OpenShift中進行部署。一直以來，我都在使用DataSource bean遇到錯誤，並且不知道我做錯了什么。

在日志中顯示：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [clanwar/config/MainConfig.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.sql.DataSource clanwar.config.MainConfig.dataSource()] threw exception; nested exception is java.lang.NullPointerException

您可以在此處檢查完整的堆棧跟蹤： http : //clanwaropenshift-stel.rhcloud.com/

我的數據源bean：

@Bean
public DataSource dataSource() {
    SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
    Driver driver = null;
    try {
        driver = new com.mysql.jdbc.Driver();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    dataSource.setDriver(driver);
    dataSource.setUrl(env.getProperty(JDBC_URL));
    dataSource.setUsername(env.getProperty(JDBC_USER));
    dataSource.setPassword(env.getProperty(JDBC_PASSWORD));
    return dataSource;
}

我也嘗試使用DriverManagerDataSource和org.apache.commons.dbcp.BasicDataSource但是org.apache.commons.dbcp.BasicDataSource都出現相同的錯誤。

提前致謝。

部署應用程序時，記錄器顯示的創建次數是dataSource的兩倍。 首先顯示：env-> StandardServletEnvironment {activeProfiles=[], defaultProfiles=[default], propertySources=[servletConfigInitParams,servletContextInitParams,jndiProperties,systemProperties,systemEnvironment,class path resource [application.properties]]}數據源-> com.mysql.jdbc.Driver@b8dec7

但是第二次顯示： com.mysql.jdbc.Driver@1133cea > null數據源-> com.mysql.jdbc.Driver@1133cea

Answer 1

我的問題是在web.xml和spring-mvc-dispatcher.xml上，我有<component-scan ...> ，它們兩次創建配置（我不知道為什么）。 除去標簽<component-scan ...>我解決了所有問題。
