Spring Boot:使用不同的Tomcat版本

时间:2016-12-21 10:01:53

标签: java tomcat spring-boot

在Spring Boot Documentation中有一节Use Tomcat 7.x or 8.0 with Gradle 这对于Maven非常有用,如一些spring-boot-samples中所示,但遗憾的是不适用于Gradle。

有没有比从tomcat-starter中排除所有tomcat依赖项更简单的解决方案,并将它们与另一个版本分开添加?

重现: 如果将示例项目spring-boot-sample-tomcat80-ssl转换为具有以下依赖项的Gradle项目:

dependencies {
    compile("org.springframework.boot:spring-boot-starter:1.4.2.RELEASE")
    compile("org.springframework.boot:spring-boot-starter-tomcat:1.4.2.RELEASE")
    compile("org.springframework:spring-webmvc:4.3.4.RELEASE")
    compile("org.apache.httpcomponents:httpclient:4.5.2")
    compile("org.apache.tomcat:tomcat-juli:8.0.36")
    compile("org.yaml:snakeyaml:1.17")
    testCompile 'org.springframework.boot:spring-boot-starter-test:1.4.2.RELEASE'
}

gradlew dependencies的输出如下所示:

compile - Dependencies for source set 'main'.

执行SampleTomcatSslApplicationTests您可以在日志中看到错误的Tomcat版本:

2016-12-21 10:20:36.713  INFO 11368 --- [           main] o.apache.catalina.core.StandardService   : Starting service Tomcat
2016-12-21 10:20:36.714  INFO 11368 --- [           main] org.apache.catalina.core.StandardEngine  : Starting Servlet Engine: Apache Tomcat/8.5.6

  • 使用spring boot gradle plugin - >魔法来了
  • 在构建脚本中设置ext['tomcat.version'] = '8.0.36'

我已就问题you've created回复了你。在您告诉我们我们的文档错误之后,我花了一些时间build a sample完全符合is referenced in the doc

如果这对您不起作用,您必须更具体,并解释文档中的错误。
