使用Spring-Boot启动Tomcat上下文时出错：java.lang.ClassNotFoundException：org.apache.tomcat.dbcp.dbcp.BasicDataSource [英] Error starting Tomcat context with Spring-Boot: java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSource

问题描述

我最近决定将spring-boot添加到现有的使用由java代码配置的hibernate的spring项目中。我有这个pom.xml文件：

 <？xml version =1.0encoding =UTF-8？> ; 
< project xmlns =http://maven.apache.org/POM/4.0.0xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance

当我尝试运行这些应用程序时（命令：mvn compile / mvn package / java -jar） ，我得到这个错误：

pre $ 引起：java.lang.ClassNotFoundException：org.apache.tomcat.dbcp.dbcp.BasicDataSource在java.net.URLClassLoader上

任何人可以告诉我我在想什么g在这里？

解决方案

在这里发布两个答案（一个被删除）后，我将这两个依赖关系添加到我的pom.xml ：

 <依赖关系> 
< groupId> org.springframework.boot< / groupId> 
< artifactId> spring-boot-starter-data-jpa< / artifactId> 
< /依赖关系> 
< dependency> 
< groupId> commons-dbcp< / groupId> 
< artifactId> commons-dbcp< / artifactId> 
< /依赖关系> 
  

并删除这三个：

 < dependency> 
< groupId> org.hibernate< / groupId> 
< artifactId> hibernate-core< / artifactId> 
< version> 4.3.6.Final< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.springframework< / groupId> 
< artifactId> spring-orm< / artifactId> 
< /依赖关系> 
< dependency> 
< groupId> org.springframework< / groupId> 
< artifactId> spring-tx< / artifactId> 
< /依赖关系> 
  

这就解决了这个问题。

I recently decide add spring-boot to a existing spring project which uses hibernate configured by java code. I have this pom.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-taglibs</artifactId>
            </dependency>
        <dependency>

            </plugin>
        </plugins>
    </build>

</project>

When I try run the applications (after the commands: mvn compile / mvn package / java -jar ), I get this error:

Caused by: java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSource
    at java.net.URLClassLoader$1.run(URLClassLoader.java:366)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
    ... 136 common frames omitted

anyone can tell me what I am missing here?

解决方案

Following the two answers posted here (one was deleted), I add this two dependencies to my pom.xml:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>commons-dbcp</groupId>
        <artifactId>commons-dbcp</artifactId>
    </dependency>

and remove this three:

   <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-core</artifactId>
       <version>4.3.6.Final</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-orm</artifactId>
        </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-tx</artifactId>
        </dependency>

and this solve the problem.
