[英]Tomcat7 + Maven plugin: Tomcat will not start with my war
I'm using java 8
and tomcat 7
and maven 3.3.9
with the maven tomcat plugin: 我正在使用
java 8
和tomcat 7
和maven 3.3.9
与maven tomcat插件:
<build>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>8085</port>
</configuration>
</plugin>
</plugins>
</build>
For a while everything worked just fine and tomcat7:run-war
worked. 有一段时间一切正常,
tomcat7:run-war
工作。
And now I'm getting this error for no apparent reason: 现在我没有明显的理由得到这个错误:

This is the error: 这是错误:
Tomcat: Failed to start component [StandardServer[-1]]: Failed to start component [StandardService[Tomcat]]: Failed to start component [StandardEngine[Tomcat]]: Failed to start component [Realm[MemoryRealm]]: Memory database file /Users/shikloshi/java_workspace/webapp-examples/tomcat-example/target/tomcat/conf/tomcat-users.xml cannot be read -> [Help 1]
Who is responsible for writing the tomcat configuration inside my target dir and why is it not written? 谁负责在我的目标目录中编写tomcat配置,为什么不写?
Execute mvn clean
in order to clean target dir. 执行
mvn clean
以清理目标目录。
Then try again, the tomcat-maven-plugin would re-create the tomcat folder (including the file tomcat-users.xml
). 然后再试一次,tomcat-maven-plugin将重新创建tomcat文件夹(包括文件
tomcat-users.xml
)。
Just delete the target folder from your application and run your app again. 只需从应用程序中删除目标文件夹,然后再次运行您的应用。 It works for me.
这个对我有用。
You can try creating a file for tomcat users in: 您可以尝试在以下位置为tomcat用户创建文件:
/Users/shikloshi/java_workspace/webapp-examples/tomcat-example/target/tomcat/conf/
And then adding this into it: 然后将其添加到其中:
<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="admin"/>
<role rolename="manager"/>
<user username="admin" password="admin" roles="tomcat,admin,manager"/>
</tomcat-users>
