SpringBoot項目部署到外部Tomcat中的方法

SpringBoot項目部署到外部Tomcat中的方法

1. 特別說明

• 因爲SpringBoot默認訪問無需項目名，因此打包成war的SpringBoot項目也須要部署成不須要輸入項目名的方式，不然資源沒法訪問，後面會給部署示例

• 官方教程地址

pom.xml調整

1.1 打包方式修改

<packaging>jar</packaging>

變動爲

<packaging>war</packaging>

1.2. 添加依賴

重點：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

不排除也沒影響，多個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. 註釋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. 啓動類修改

繼承SpringBootServletInitializer覆蓋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. 省略項目名部署方法

修改TOMCAT的server.xml，demo是項目文件夾

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