Mapper.xml can't get in when Maven packs.

First, look at the directory structure of the MAVENX Project Standard:

In general, the resource files we use (various xml,properites,xsd files, etc.) are placed under Src/main/resources, and MAVEN can package these resource files into the appropriate jar or war using MAVEN.

Sometimes, such as MyBatis's Mapper.xml file, we used to put it and Mapper.java together, all under the Src/main/java, so using maven packaging, You will need to modify the Pom.xml file to package the Mapper.xml file into a jar or war, otherwise these files will not be packaged. (Maven thinks Src/main/java is just Java's source code path). There are many methods on the network, I probably tried, several methods can be, can choose one.

Method 1, where **/* is written in order to ensure that the resource files under all levels of subdirectories are packaged.

XML code

<Build>    <Finalname>Test</Finalname>    <!--This also allows all XML files to be packaged in the appropriate location. <resources> <resource> <directory>src/main/resources</directory> < Includes> <include>**/*.properties</include> <include>**/*.xml</incl ude> <include>**/*.tld</include> </includes> <filtering>fa lse</filtering><--here is false, the database connection error is reported with true-</resource> <resource> < ;d irectory>src/main/java</directory> <includes> <include>**/*.properties< ;/include> <include>**/*.xml</include> <include>**/*.tld</include>            ; </includes> <filtering>false</filtering> </resource> </resources></b Uild>

Method 2, using the Build-helper-maven-plugin plugin

<Build>    ...    </Plugins>        ...        <!--This plugin can be used to take advantage of this plugin, the source code in the XML file, packaging to the appropriate location, here is mainly to package MyBatis Mapper.xml file -        <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>

Method 3, using the Maven-resources-plugin plugin

<Build>    ...    </Plugins>        ...        <!--This plugin can be used to take advantage of this plugin, the source code in the XML file, packaging to the appropriate location, here is mainly to package MyBatis Mapper.xml file -        <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>
