如何将SpringBoot Web应用程序部署到Tomcat？在springboot上部署工作，在tomcat上不行

问题描述 投票：0回答：1

好，所以我将Spring应用程序部署为.war文件。

在Spring Boot嵌入式服务器上，一切正常，但是当我尝试在Tomcat上部署它时我得到以下堆栈跟踪。

我正在使用自动装配的EntityManager在数据库上工作。使用Application.properties文件中的数据创建DataSource对象。

我在stackoverflow等上寻找答案，但无法使其正常工作。还尝试手动创建一个entityManager Bean，而不是使用SpringBoot提供的bean，但这对我不起作用。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [pl/jakubz/simplehouse/config/JNDIConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'appDataSource' defined in class path resource [pl/jakubz/simplehouse/config/JNDIConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'appDataSource' threw exception; nested exception is java.lang.NullPointerException

我应该如何配置tomcat使其正常工作？

我看到您的代码有几个问题，这些问题可能导致独立的tomcat中的应用程序初始化不正确。

  1. 您应将<packaging>war</packaging>添加到pom.xml文件中。目前，我在您的存储库中看不到它。

  2. 您应将tomcat从战争档案中排除，因为您要将文件部署到独立的tomcat：

    <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>

  3. 您应该从SpringBootServletInitializer扩展您的主要springboot入门类

    @ SpringBootApplication公共类BackenddemoApplication扩展了SpringBootServletInitializer {....}
