摘要：这个内置的tomcat是在spring-boot-starter-web这个start中引入的，所以说：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屏蔽掉如果你的项目里面没用到这个starter，就不

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"?>

        <module>micro-service-run</module>

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"?>

    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

            </plugin>
        </plugins>
    </build>

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"?>

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。
