SpringBoot项目部署到外部Tomcat中的方法

1. 特别说明

由于SpringBoot默认访问无需项目名，所以打包成war的SpringBoot项目也需要部署成不需要输入项目名的方式，否则资源无法访问，后面会给部署示例

官方教程地址

pom.xml调整

1.1 打包方式修改

<packaging>jar</packaging>

变更为

<packaging>war</packaging>

1.2. 添加依赖

重点：scope是provided

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

1.3. 排除嵌入式tomcat

不排除也没影响，多个jar而已

<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>

1.4. 注释spring-boot-maven-plugin，使用maven-war-plugin

<!-- 
<plugin>
    <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>bing.AuthorityApplication</mainClass> <layout>ZIP</layout> </configuration> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <configuration> <failOnMissingWebXml>false</failOnMissingWebXml> </configuration> </plugin>

2. 启动类修改

继承SpringBootServletInitializer覆盖configure方法，示例：

public class Application extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) { return builder.sources(Application.class); } public static void main(String[] args) { new SpringApplicationBuilder(Application.class).web(true).run(args); } }

3. 省略项目名部署方法

修改TOMCAT的server.xml，demo是项目文件夹

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true"> ... <Context path="" docBase="D:/opt/demo" debug="0" reloadable="true"/> ... </Host>
