maven 结合mybaits整合框架时遇到的问题

首先，来看下MAVENx项目标准的目录结构：

 

一般情况下，我们用到的资源文件（各种xml，properites，xsd文件等）都放在src/main/resources下面，利用maven打包时，maven能把这些资源文件打包到相应的jar或者war里。

 

有时候，比如mybatis的mapper.xml文件，我们习惯把它和Mapper.java放一起，都在src/main/java下面，这样利用maven打包时，就需要修改pom.xml文件，来把mapper.xml文件一起打包进jar或者war里了，否则，这些文件不会被打包的。（maven认为src/main/java只是java的源代码路径）。网络上有很多方法，我大概试了下，几种方法都可以，可以任选一种即可。

 

方法1，其中**/*这样的写法，是为了保证各级子目录下的资源文件被打包。

xml代码

<build>
    <finalName>test</finalName>
    <!--
    这样也可以把所有的xml文件，打包到相应位置。
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>**/*.tld</include>
            </includes>
            <filtering>false</filtering><--这里是false，用true会报 数据库连接 错误-->
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>**/*.tld</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

方法2，利用build-helper-maven-plugin插件

<build>
    ...
    </plugins>
        ...
        <!--
        此plugin可以用
        利用此plugin，把源代码中的xml文件，
        打包到相应位置，这里主要是为了打包Mybatis的mapper.xml文件 
        -->
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>build-helper-maven-plugin</artifactId>
            <version>1.8</version>
            <executions>
                <execution>
                    <id>add-resource</id>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>add-resource</goal>
                    </goals>
                    <configuration>
                        <resources>
                            <resource>
                                <directory>src/main/java</directory>
                                <includes>
                                    <include>**/*.xml</include>
                                </includes>
                            </resource>
                        </resources>
                    </configuration>
                </execution>
            </executions>
        </plugin>   
        ...
    </plugins>     
    ...
</build>

方法3，利用maven-resources-plugin插件

<build>
    ...
    </plugins>
        ...
        <!--
        此plugin可以用
        利用此plugin，把源代码中的xml文件，打包到相应位置，
        这里主要是为了打包Mybatis的mapper.xml文件 
        -->
        <plugin>
            <artifactId>maven-resources-plugin</artifactId>
            <version>2.5</version>
            <executions>
                <execution>
                    <id>copy-xmls</id>
                    <phase>process-sources</phase>
                    <goals>
                        <goal>copy-resources</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${basedir}/target/classes</outputDirectory>
                        <resources>
                            <resource>
                                <directory>${basedir}/src/main/java</directory>
                                <includes>
                                    <include>**/*.xml</include>
                                </includes>
                            </resource>
                        </resources>
                    </configuration>
                </execution>
            </executions>
        </plugin>   
        ...
    </plugins>     
    ...
</build>
