Failed to load main class while executing war

I build my project using maven and generated a *.war file with the following content structure:

我使用maven构建我的项目并生成一个* .war文件,其中包含以下内容结构:

META-INF
- maven
-- net.avedo.spozz
--- Spozz-Webservice
---- pom.properties
---- pom.xml
- MANIFEST.MF
WEB-INF
- classes
-- net
--- avedo
---- spozz
----- Spozz.class
----- models
------ ...
----- services
------ ...
-- psql-custom.properties
- lib
-- ...
- web.xml

If I now try to run the generated war file using java -jar spozz.war, I get the following error:

如果我现在尝试使用java -jar spozz.war运行生成的war文件,我会收到以下错误:

Error: Could not find or load main class net.avedo.spozz.Spozz

What did I wrong? Please find the Manifest file and the definition of the maven-war-plugin in the pom.xml below.

我错了什么?请在下面的pom.xml中找到Manifest文件和maven-war-plugin的定义。

2 个解决方案

#1

The simplest way I know to launch a .war file as a Web application is with Jetty Runner:

我知道将.war文件作为Web应用程序启动的最简单方法是使用Jetty Runner:

Download jetty-runner.jar
Run java -jar jetty-runner.jar spozz.war

运行java -jar jetty-runner.jar spozz.war

Access your Web application at localhost:8080

在localhost访问您的Web应用程序:8080

#2

A normal jar file has its class files in the jar file root. Your class files are in WEB-INF\classes which is the normal position for a war (web application).

普通的jar文件在jar文件根目录中有其类文件。您的类文件位于WEB-INF \ classes中,这是战争(Web应用程序)的正常位置。

You could use the already mentioned jetty approach or relayout your archive file.

您可以使用已经提到的jetty方法或重新布局您的存档文件。

Jar
     Myclass.class
     Mymain.class
     META-INF
            manifest

But maybe you do not want an executable war. Then you have to create a Jar using maven.

但也许你不想要一场可执行的战争。然后你必须使用maven创建一个Jar。
