部署jar Tomcat 8

Question

i've not developed for a long time.

Now i'm starting developing again. I've built spring boot application, but unfortunately after "Maven:Install" in Intellij a copy the file to Tomcat 8, Tomcat don't deploy the app.

In server.xml i have autoDeploy="true"

The build section in pom.xml is:

<build>
    <finalName>ROOT</finalName>
    <plugins>
        <plugin>
            <artifactId>maven-eclipse-plugin</artifactId>
            <version>2.9</version>
            <configuration>
                <additionalProjectnatures>
                    <projectnature>org.springframework.ide.eclipse.core.springnature</projectnature>
                </additionalProjectnatures>
                <additionalBuildcommands>
                    <buildcommand>org.springframework.ide.eclipse.core.springbuilder</buildcommand>
                </additionalBuildcommands>
                <downloadSources>true</downloadSources>
                <downloadJavadocs>true</downloadJavadocs>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.5.1</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <compilerArgument>-Xlint:all</compilerArgument>
                <showWarnings>true</showWarnings>
                <showDeprecation>true</showDeprecation>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>1.2.1</version>
            <configuration>
                <mainClass>org.test.int1.Main</mainClass>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

Of course Tomcat works fine.

In catalina there is no info, that tomcat is trying to deploy - exactly nothing.

Could you support me, what i forgot?

Answer 1

if you develop a spring boot application , you don't need to copy file to tomcat. You have only to run the generated jar file with:

'java -jar jarFileName.jar'

and will start the application. The tomcat is included in the jar file

Answer 2

TO be able to deploy your spring boot application as .war file to tomcat server you need the following prerequsites:

1. add spring-boot-maven plugin to your pom.xml

     <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>${springboot.version}</version> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> 

2. You should make your SpringBootApplication extend SpringBootServletInitializer

    @SpringBootApplication public class YourSpringBootApplication extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(YourSpringBootApplication .class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(YourSpringBootApplication .class); } }
