Redshift jdbc连接配置与Spring启动2无法正常工作

[英]Redshift jdbc connection configuration with Spring boot 2 not working

 原文  2018-06-29 13:33:51  3   1    java/ spring-boot/ amazon-redshift/ spring-jdbc/ spring-web

问题描述

这是我在build.gradle中的依赖项。 

compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.0.2.RELEASE'
compile group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa', version: '2.0.3.RELEASE'
compile group: 'postgresql', name: 'postgresql', version: '9.1-901-1.jdbc4'
compile group: 'com.amazon.redshift', name: 'redshift-jdbc42', version: '1.2.10.1009'
compile group: 'org.eclipse.jetty', name: 'jetty-util', version: '9.4.11.v20180605'
compile group: 'org.hibernate', name: 'hibernate-java8', version: '5.0.0.CR1'
compile group: 'com.vladmihalcea', name: 'hibernate-types-52', version: '2.2.2'

当我启动我的应用程序时，它无法启动tomcat服务器。 我收到了以下错误，

我在网上尝试了所有类型的解决方案，关于tomcat没有运行，比如将redshift依赖项更改为noawssdk模块，更改ctomcat verion等，但没有一个对我有用。 有人可以帮我吗？

看起来Redshift从其JarInJarClassLoader类调用URL.setURLStreamHandlerFactory() ，而嵌入式Tomcat也从org.apache.catalina.webresources.TomcatURLStreamHandlerFactory.调用相同的方法org.apache.catalina.webresources.TomcatURLStreamHandlerFactory. 这是URL.setURLStreamHandlerFactory()样子： 

  /**
 * Sets an application's {@code URLStreamHandlerFactory}.
 * This method can be called at most once in a given Java Virtual
 * Machine.
 *
 *<p> The {@code URLStreamHandlerFactory} instance is used to
 *construct a stream protocol handler from a protocol name.
 *
 * <p> If there is a security manager, this method first calls
 * the security manager's {@code checkSetFactory} method
 * to ensure the operation is allowed.
 * This could result in a SecurityException.
 *
 * @param      fac   the desired factory.
 * @exception  Error  if the application has already set a factory.
 * @exception  SecurityException  if a security manager exists and its
 *             {@code checkSetFactory} method doesn't allow
 *             the operation.
 * @see        java.net.URL#URL(java.lang.String, java.lang.String,
 *             int, java.lang.String)
 * @see        java.net.URLStreamHandlerFactory
 * @see        SecurityManager#checkSetFactory
 */
public static void setURLStreamHandlerFactory(URLStreamHandlerFactory fac) {
    synchronized (streamHandlerLock) {
        if (factory != null) {
            throw new Error("factory already defined");
        }
        SecurityManager security = System.getSecurityManager();
        if (security != null) {
            security.checkSetFactory();
        }
        handlers.clear();
        factory = fac;
    }
}

如您所见，每个JVM只能调用一次。 因此，似乎解决方案是停止Redshift或嵌入式Tomcat调用该方法。 看起来TomcatURLStreamHandlerFactory.disable()会阻止嵌入式Tomcat这样做，但我不确定会产生什么额外后果。 我没有找到这个的话题，这似乎意味着有副作用的讨论。 另一个选择可能是在Tomcat启动后加载Redshift驱动程序，假设Redshift代码正确处理该条件。 从快速搜索后我可以看出，驱动程序不是开源的，所以我无法验证是否可行。 另一个选择是从Tomcat切换到另一个嵌入式servlet容器 - 我尝试切换到Jetty，这似乎对我有用。
