SpringBoot - resource资源文件的打包配置详解（指定资源文件位置）

SpringBoot - resource资源文件的打包配置详解（指定资源文件位置）

1，问题描述

（1）默认 Spring Boot 项目结构，资源文件放置在 src/main/resources 中，测试的资源文件在 src/test/resources 中。

src/main/resources src/test/resources的区别：

（2）将项目打包后，解压 可以发现原先

（3）但有时我们的资源文件并不一定是放在 src/main/resources目录下，比如我的项目通常会将资源文件放在src/test/resources

**原因：**根据实践经验表明，测试完后的配置项是最完整的，且经常会忘记替换正式版参数，因而选择将配置文件全部放置在 src/test/resources 目录下。

（4）又比如 mybatis 的 mapper.xml 文件，我们习惯把它和 Mapper.java 放一起

（5）但上面这两种情况的资源文件，在使用 maven 打包时是不会被打包进 jar 的。这时候我们便要指定需要打包的资源文件，这个有如下两种方法可以实现。

2，使用 标签

（1） 标签位于 标签内，用于指定项目资源文件的位置。比如下面配置我们指定了 src/test/resources 也是资源文件目录：

`<``build``>``  ``<``plugins``>``    ``<``plugin``>``      ``<``groupId``>org.springframework.boot`groupId``>``      ``<``artifactId``>spring-boot-maven-plugin`artifactId``>``    ```plugin``>``  ```plugins``>``  ``````<``resources``>``    ``<``resource``>``      ``<``directory``>src/test/resources`directory``>``    ```resource``>``    ``<``resource``>``      ``<``directory``>src/main/resources`directory``>``    ```resource``>``  ```resources``>```build``>`

（2）而对于写在包下的Mapper.xml

提示：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。

`<``build``>``  ``<``plugins``>``    ``<``plugin``>``      ``<``groupId``>org.springframework.boot`groupId``>``      ``<``artifactId``>spring-boot-maven-plugin`artifactId``>``    ```plugin``>``  ```plugins``>``  ``````<``resources``>``    ``<``resource``>``      ``<``directory``>src/main/java`directory``>``      ``<``includes``>``        ``<``include``>**/*.xml`include``>``      ```includes``>``    ```resource``>``    ``<``resource``>``      ``<``directory``>src/main/resources`directory``>``    ```resource``>``  ```resources``>```build``>`

（3）我们还可以通过excludes

`<``build``>``  ``.......``  ``<``resources``>``    ``<``resource``>``      ``<``directory``>src/main/resources`directory``>``      ``<``excludes``>``        ``<``exclude``>**/*.properties`exclude``>``        ``<``exclude``>**/*.xml`exclude``>``      ```excludes``>``      ``<``filtering``>false`filtering``>``    ```resource``>``    ``<``resource``>``      ``<``directory``>src/main/java`directory``>``      ``<``includes``>``        ``<``include``>**/*.properties`include``>``        ``<``include``>**/*.xml`include``>``      ```includes``>``      ``<``filtering``>false`filtering``>``    ```resource``>``  ```resources``>``  ``......```build``>`

3，使用 maven-resources-plugin 插件

（1） 除了使用 标签外，我们也可以使用 maven-resources-plugin 插件实现同样的目的。比如下面配置把 src/test/resources 目录下的资源文件打包到 classes 目录下

    
        
            org.springframework.boot
            spring-boot-maven-plugin
        
        
            org.apache.maven.plugins
            maven-resources-plugin
            
                
                    my-resources
                    process-resources
                    
                        copy-resources
                    
                     	${basedir}/target/classes
                        
                            
                                ${basedir}/src/test/resources
                                
                                    *.properties
                                    *.xml
                                
                            
                        
                    
                
            
        
    

（2）而对于写在包下的Mapper.xml maven-resources-plugin插件将其打包到相应位置：

`<``build``>``  ``<``plugins``>``    ``<``plugin``>``      ``<``groupId``>org.springframework.boot`groupId``>``      ``<``artifactId``>spring-boot-maven-plugin`artifactId``>``    ```plugin``>``    ``<``plugin``>``      ``<``groupId``>org.apache.maven.plugins`groupId``>``      ``<``artifactId``>maven-resources-plugin`artifactId``>``      ``<``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``>`

（3）使用maven-resources-plugin插件时，我们同样可以通过excludes

`<``build``>``  ``<``plugins``>``    ``<``plugin``>``      ``<``groupId``>org.springframework.boot`groupId``>``      ``<``artifactId``>spring-boot-maven-plugin`artifactId``>``    ```plugin``>``    ``<``plugin``>``      ``<``groupId``>org.apache.maven.plugins`groupId``>``      ``<``artifactId``>maven-resources-plugin`artifactId``>``      ``<``executions``>``        ``<``execution``>``          ``<``id``>my-resources`id``>``          ``<``phase``>process-resources`phase``>``          ``<``goals``>``            ``<``goal``>copy-resources`goal``>``          ```goals``>``          ``<``configuration``>``            ``<``outputDirectory``>${basedir}/target/classes`outputDirectory``>``            ``<``resources``>``              ``<``resource``>``                ``<``directory``>${basedir}/src/test/resources`directory``>``                ``<``includes``>``                  ``<``include``>**/*.*`include``>``                ```includes``>``                ``<``excludes``>``                  ``<``exclude``>log4j2-spring.xml`exclude``>``                ```excludes``>``              ```resource``>``            ```resources``>``          ```configuration``>``        ```execution``>``      ```executions``>``    ```plugin``>``  ```plugins``>```build``>`
