springboot 打war包

使用版本：

springboot 2.0.0

jdk 8

tomcat 8.50以上

低版本的tomcat可能会报错

Invalid byte tag in constant pool : 19

修改pom.xml

<packaging>war</packaging>

<dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

            <exclusions>

                <exclusion>

                    <groupId>org.springframework.boot</groupId>

                    <artifactId>spring-boot-starter-tomcat</artifactId>

                </exclusion>

            </exclusions>

        </dependency>

去掉starter中内嵌的tomcat引用

增加plugin war

<build>

        <plugins>

            <plugin>

                <artifactId>maven-war-plugin</artifactId>

                <configuration>

                    <warName>${project.name}</warName>

                    <failOnMissingWebXml>false</failOnMissingWebXml>

                </configuration>

            </plugin>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

                <version>${spring-boot.version}</version>

                <executions>

                    <execution>

                        <goals>

                            <goal>repackage</goal>

                        </goals>

                    </execution>

                </executions>

            </plugin>

            </plugins>

    </build>

修改代码

application.source的入参为入口类WebApplication

@ServletComponentScan

public class ServletInitializer extends SpringBootServletInitializer {

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        logger.info("开始启动项目。。。ServletInitializer");

        return application.sources(WebApplication.class);

    }

}
