springboot war包注意事项

//war包需要在pom配置手动导入本地jar包，以避免本地jar包无法导入问题
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version> 3.0.0</version>
    <configuration>
        <webResources>
            <resource>
                <directory>/src/lib</directory>
                <targetPath>WEB-INF/lib/</targetPath>
                <includes>
                    <include>**/*.jar</include>
                </includes>
            </resource>
        </webResources>
    </configuration>
</plugin>

springboot自带tomcat 因此如果war包部署到tomcat或者国产东方通等容器时，需要删除自身tomcat。

原生springboot删除方式：

<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>

如果springboot集成如模板引擎或其他组件时，则单独删除，如：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

将原本

<packaging>jar</packaging>

改为

<packaging>war</packaging>

在Application启动类中继承SpringBootServletInitializer抽象类重写configure方法已使用外部的Servlet容器

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
{
    return application.sources(Application.class);
}

随后通过maven clean命令清除原有包，通过maven package打包即可
