Question

我正在使用以下工具开发应用程序：

码头-行家-插件：9.3.2.v20150730
tomcat-jdbc：8.0.8（以tomcat-juli为依赖）

尝试将tomcat-jdbc jar升级到8.0.9+以上的任何版本后，我收到以下错误：

java.util.ServiceConfigurationError：org.apache.juli.logging.Log：提供者org.eclipse.jetty.apache.jsp.JuliLog不是子类型

查看这两个版本之间的更改日志，我发现了一些看似可疑的内容：

＆＃34;将一个简单的基于ServiceLoader的发现机制添加到JULI LogFactory，以便更容易地独立于Tomcat使用依赖于JULI的JULI和Tomcat组件（如Jasper）。补丁由Greg Wilkins提供。（Markt的）＆＃34;

此外，我发现Apache Tomcat JDBC连接池中引入了新的系统属性：

org.apache.tomcat.jdbc.pool.onlyAttemptCurrentClassLoader

＆＃34;控制动态类的类加载，例如JDBC驱动程序，拦截器和验证器。如果设置为false，默认值，则池将首先尝试使用当前加载器（即加载池类的类加载器）加载，如果类加载失败，则尝试使用线程上下文加载器加载。如果您希望向后兼容Apache Tomcat 8.0.8及更早版本，并且仅尝试当前加载器，请将此值设置为true。如果未设置，则默认值为false。＆＃34;

不幸的是，使用jetty启动插件：使用此属性运行并没有解决问题。

任何帮助将不胜感激！谢谢！

Answer 1

Spring Boot starter web依赖项默认包含tomcat。当你启动它时，这会混淆jetty，因为它使用不同版本的juli lib。

只需修复你的pom.xml，排除starter-tomcat并单独包含jetty依赖：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jetty</artifactId>
    </dependency>

Answer 2

看来，这是由Jetty使用修改后的Apache JSP包Jasper引起的。它有自己的Juli日志记录版本（在Jetty主目录下检查lib/apache-jsp/org.mortbay.jasper.apache-jsp-8.0.27.jar），这似乎引起了所有的困惑。我认为，Jetty的默认webapp class loading logic会在每次请求类时从您的webapp中加载Juli LogFactory。当LogFactory必须加载tomcat-jdbc类时，这一切都很好。当它通过Jetty的修改过的Jasper类时会变得棘手，因为它意识到存在类型冲突。

如何解决这个问题？我认为有两种方法可以做到这一点：

<强> 1。更改Jetty webapp类加载器逻辑

您可以修改类加载器逻辑，始终将类加载委托给父类加载器。您只需在特定setParentLoaderPriority(true)上致电WebAppContext即可。您可以通过Jetty配置或将jetty-web.xml文件包含在战争中来实现。

<强> 2。排除tomcat-juli依赖

使用Maven的Dependency exclusions，您可以跳过任何您不喜欢的传递依赖。因此，只需添加tomcat-jdbc而不是tomcat-juli，就可以了。

唯一的问题是两种解决方案都会强迫您使用Jetty修改过的Juli包。还没有看到这种情况有问题，但我想在某些时候你可能会发现你错过了一些功能，因为Jetty修改后的Juli没有与Apache最新版本同步。

Answer 3

如果这不是一个春季项目

这是我在pom.xml中提供的排除项：

NavigationLink(destination: ProductsView(), isActive: $photosLibraryHelper.authorized) {
    EmptyView()
}

还提供了插件：

        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>9.4.24.v20191120</version>
             <exclusions>
                <exclusion>
                    <groupId>org.eclipse.jetty</groupId>
                    <artifactId>apache-jsp</artifactId>
                </exclusion>
             </exclusions>
        </dependency>

使用上述排除方法apache-jsp（Jule Logging），我没有收到该异常。

希望这会有所帮助。!!!
