springboot项目打war包

1 .      声明打包格式

<packaging>war</packaging>

2.  声明打包依赖

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.0.1</version>
</dependency>

3. 移除嵌入式Tomcat

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <!-- 移除嵌入式tomcat插件 -->
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

4. 在与启动类统一路径下建立SpringBootStartApplication类,继承SpringBootServletInitializer

import javafx.application.Application;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
* 修改启动类，继承 SpringBootServletInitializer 并重写 configure 方法
*/
public class SpringBootStartApplication extends SpringBootServletInitializer {

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// 注意这里要指向原先用main方法执行的Application启动类
return builder.sources(Application.class);
}
}

5.   双击Maven下的package

6.打包完成, 自动保存在target目录下

如果用了外部jar 包

添加下面的配置

<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
<!-- 项目打包 添加外部 lib -->
<compilerArguments>
<extdirs>${basedir}/libs</extdirs>
</compilerArguments>
</configuration>
</plugin>
<!-- tomcat7插件 -->
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>9999</port>
<uriEncoding>UTF-8</uriEncoding>
</configuration>
</plugin>

另一种打包方式:

路径更具上面的自定义路径找到war包即可
