篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了springboot多模块项目打war包相关的知识，希望对你有一定的参考价值。
一、父模块配置
1，指定pakaging:pom
2，指定编译的版本：如下图：
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.7</java.version> </properties>
3，屏蔽内置的tomcat:
（1）这个内置的tomcat是在spring-boot-starter-web这个start中引入的，所以说：
1）如果你的项目里面用到了这个starter（如下），就加上下面蓝色框中的代码将内置的tomcat屏蔽掉
2）如果你的项目里面没用到这个starter，就不会有内置的tomcat，这一条就可以跳过。
3）在大多数项目中都是有用到这个starter中的，而且可能很多子模块中也用到了这个starter，所以可以在父模块中添加（子模块中不需要在添加），并屏蔽内置tomcat，如下：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!--忽略内嵌tomcat，打包部署到tomcat。注*本地运行的时候要把这一段忽略引入个注释掉，要不然项目启动不了 --> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency>
4， 关于对子模块的依赖:
（1）没有用到子模块可以不写
（2）用到哪个配哪个：如下：
<dependencyManagement> <dependencies> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-static</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-infrasture</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-user</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-service-autho</artifactId> <version>${project.version}</version> </dependency> </dependencies> </dependencyManagement>
5，子模块配置：
<modules> <module>micro-service-static</module> <module>micro-service-infrasture</module> <module>micro-servcice-user</module> <module>micro-service-autho</module> <module>micro-service-run</module> </modules>
6，配置文件配置（该设置可在父模块中统一设置，也可以在子模块中单独设置）
在没有配置的时候报错，找不到transaction.xml。
出错原因：配置文件没有打进war包
需要做如下配置：
<!-- 解决读不到配置文件的问题，将指定的文件打进war包 -->
<resources>
<resource>
<!-- 要打进war包的文件所在的目录 -->
<directory>src/main/resorce</directory>
<includes>
<include>**.*</include>
<include>**/*.*</include>
<include>**/*/*.*</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
7，父模块完整的xml
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.18.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <groupId>com.googosoft.microservice</groupId> <artifactId>googosoft-micro-service</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>pom</packaging> <name>googosoft-micro-service</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.7</java.version> </properties> <!-- 只配置依赖到的即可 --> <!-- <dependencyManagement> <dependencies> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-static</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-infrasture</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-user</artifactId> <version>${project.version}</version> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-service-autho</artifactId> <version>${project.version}</version> </dependency> </dependencies> </dependencyManagement> --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- 在父模块中配置，子模块无需在配置 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!--忽略内嵌tomcat，打包部署到tomcat。注*本地运行的时候要把这一段忽略引入个注释掉，要不然项目启动不了 --> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <!--用于编译jsp --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> </dependencies> <!-- 子模块配置 --> <modules> <module>micro-service-static</module> <module>micro-service-infrasture</module> <module>micro-servcice-user</module> <module>micro-service-autho</module> <module>micro-service-run</module> </modules> </project>
二、子模块-启动模块配置
1，指定父模块：
<parent> <groupId>com.googosoft.microservice</groupId> <artifactId>googosoft-micro-service</artifactId> <version>0.0.1-SNAPSHOT</version> </parent>
2，packaging设置：
这里我需要一个war包，所i一指定成war
<packaging>war</packaging>
3，指定依赖的子模块
如果依赖的模块的packaging为war，就必须配置type，classifier,否则会报下错：
正确的配置：
<dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-user</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-service-autho</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-infrasture</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency>
4,打war包插件设置
<plugins> <!-- war包插件 --> <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <!-- 把class打包jar作为附件 --> <attachClasses>true</attachClasses> </configuration> </plugin> <!-- 指定启动入口 --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.googosoft.UserBootApplication</mainClass> </configuration> </plugin> </plugins>
5，指定启动入口
<!-- 指定启动入口 --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <mainClass>com.googosoft.UserBootApplication</mainClass> </configuration> </plugin>
除了上面的配置还需要加Initializer继承SpringBootServletInitializer重写SpringApplicationBuilder方法，如下：
package com.googosoft;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(UserBootApplication.class);
}
}
不重写报错：
重写后：
6，启动模块完整pom.xml
<?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>com.googosoft.microservice</groupId> <artifactId>googosoft-micro-service</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-service-run</artifactId> <version>0.0.1-SNAPSHOT</version> <name>micro-service-run</name> <packaging>war</packaging> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-user</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-service-autho</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency> <dependency> <groupId>com.googosoft.microservice</groupId> <artifactId>micro-servcice-infrasture</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- 该模块的packaging为war，所以下面两项必须设置，否则打包会出出错 --> <type>jar</type> <classifier>classes</classifier> </dependency> </dependencies> <build> <!-- 为jar包取名 --> <finalName>micro-service-run</finalName> <plugins> <!-- war包插件 --> <plugin> <artifactId>maven-war-plugin以上是关于springboot多模块项目打war包的主要内容，如果未能解决你的问题，请参考以下文章
