springboot多模块项目打war包
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">

<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"

<configuration>
<mainClass>com.googosoft.UserBootApplication</mainClass>
</configuration>
</plugin>
</plugins>
</build>
</project>
三、子模块-packaging为war的模块设置
1，packaging设置：war
设置为war后必须添加plugin
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<!-- 把class打包jar作为附件 -->
<attachClasses>true</attachClasses>
</configuration>
</plugin>
2，模块依赖设置
<dependency>
<groupId>com.googosoft.microservice</groupId>
<artifactId>micro-servcice-infrasture</artifactId>
<type>jar</type>
<classifier>classes</classifier>
<version>0.0.1-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
3，packaging为war的子模块的完整的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"

四、其他设置
（1）依赖中尽量不要引用外部jar包
（我在开始使用的下面的方式，打包）
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml-schemas</artifactId>
<version>3.15</version>
<scope>system</scope>
<systemPath>${basedir}/lib/poi-ooxml-schemas-3.15.jar</systemPath>
</dependency>
项目运行时报错：classNotFound
将后两行去掉，项目就可以正常运行了，引用外部jar包应该是可以使用的，但是可能需要额外的配置，最好不要使用。
