My project is springboot development, with the idea of development tools:
First, let's take a look at my package configuration:
<!--打war包第一步-->添加依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
将build改成：
<build>
<finalName>myweb</finalName><!--打war包第二步-->
<plugins>
<plugin>
<!--打war包第三步-->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
<-! Fight the war package Step 4 -> Add:
<Packaging> war </ Packaging>
<-! Fight the war package Step 5 -> master boot class needs to inherit something, and rewrite:
@SpringBootApplication
public class MywebApplication the extends SpringBootServletInitializer {
/ **
* need to deploy web projects labeled as war package to run outside tomcat when the need to change the start-up mode
* /
@Override
protected SpringApplicationBuilder Configure (SpringApplicationBuilder Builder) {
return builder.sources (MywebApplication.class);
}
public static void main (String [] args) {
SpringApplication.run (MywebApplication.class, args);
}
}
I am using cmd project package when appeared as the title that mistake, the Internet a bunch of garbage answer, eventually found a positive solution, I've re-installed the jdk, wrong to tell us you are sure you are using the jre instead jdk ? obviously we want to be able to configure the local maven packaged jdk, we download a good jdk, will first go to install jdk, then will follow jre, we should pay special attention both to separate out: we need to pay special attention to the configuration environment variable JAVA_HOME.
We need to add a line to set the mvn.cmd file in the maven bin directory: add to the first line.
Test: Use the cmd enter mvn -version command:
I re-downloaded jdk8_241 version. Jdk we can see that the information is downloaded jdk, it seems valid configuration, runtime and our re-download the jdk version.
If you still jdk previous version, is probably a problem with the configuration, you need to pay attention to that, we need to move on environment variables jdk the configuration of the first line:
Well, now in use cmd: mvn clean package to package, no problem.
