Tomcat 9 无法加载 Spring Boot 应用程序 [英] Tomcat 9 can't load spring boot application

问题描述

我正在将 Spring Boot 应用程序部署到现有的 Tomcat 9 实例.当 tomcat 尝试加载上下文时，出现以下错误:

I am deploying a spring boot application to an existing Tomcat 9 instance. When tomcat tries to load the context, I get the following error:

如果我自己运行应用程序，它使用嵌入式 tomcat 9 引擎运行得很好.

If I run the app by itself, it runs just fine using the embedded tomcat 9 engine.

这是我在 pom 文件中使用的 spring 依赖项:

Here's the spring dependencies I am using in pom file:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.5.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jersey</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

任何帮助将不胜感激.

推荐答案

多挖了一点，问题是拉进来的 Jersey 版本是错误的.该项目正在引入 Jersey 2.6，这是 Spring Boot 2.2.5 的错误版本.Jersey 2.6(其中有问题的类所在的 jersey-common 2.6)不包括 org/glassfish/jersey/internal/l10n/LocalizableMessageFactory$ResourceBundleSupplierclass

After digging a bit more, the problem was that the Jersey version being pulled in was the incorrect one. The project was pulling in Jersey 2.6 which is the wrong version for Spring Boot 2.2.5. Jersey 2.6 (which has jersey-common 2.6 where the class in question is) does not include the org/glassfish/jersey/internal/l10n/LocalizableMessageFactory$ResourceBundleSupplierclass

一旦我修复了 pom 文件，Tomcat 就会正确加载它.

Once I fixed the pom file, Tomcat loaded it correctly.
