我有一个适用于Spring Cloud Netflix 1.0.0.RC1的应用程序。当我升级同一个项目以使用RC2工件时,在应用程序启动期间出现以下异常。

与RC1相同的POM文件作为版本工作正常。我尝试手动将javax.el:javax.el-api:2.2.4添加到POM中,但是在使用该依赖项后,Tomcat无法正常启动(日志中没有错误,但也没有Tomcat启动)。

1 个答案:

答案 0 :(得分:0)

通过将以下依赖项添加到POM文件来实现此功能。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

似乎自RC2以来,我们需要显式添加Tomcat Starter作为依赖项。
