java - mvn包不包含xml

Question

我使用的是mybatis 3.3.1版本，并将mybatis配置文件mybatis-conf.xml放在SqlSessionFactoryManager所在目录。

我通过mvn package创建了可执行jar，但SqlSessionFactoryManager告诉一个错误

java.io.IOException: Could not find resource kr/stocktalk/mybatis/mybatis-conf.xml
at org.apache.ibatis.io.Resources.getResourceAsStream(Resources.java:114)

这是SqlSessionFactoryManager的代码片段

try {

    String resource = "kr/stocktalk/mybatis/mybatis-conf.xml";
    Reader reader = Resources.getResourceAsReader(resource);

    if (sqlSessionFactory == null) {
        sqlSessionFactory = new SqlSessionFactoryBuilder()
                .build(reader);
    }
} catch (Exception e) {
        e.printStackTrace();
}

我认为发生异常是mybatis-conf.xml未包含executable-jar

所以我尝试在里面添加include代码maven-jar-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
    <excludes>
        <exclude>logback.xml</exclude>
        </excludes>
    <includes>
        <include>**/*.xml</include>
        <include>**/*.class</include>
    </includes>
    <archive>
        <manifest>
            <mainClass>kr.stocktalk.chat.ChatServer</mainClass>
                <addClasspath>true</addClasspath>
                <classpathPrefix>lib/</classpathPrefix>
            </manifest>
        </archive>
    </configuration>
</plugin>

但是可执行 jar 文件中不包含 xml 文件。

如何包含 *.xml 文件？

这是所有 pom.xml 代码。

可以使用绝对或相对路径访问资源。您的路径 "kr/stocktalk/mybatis/mybatis-conf.xml" 是一个相对路径(相对于它所使用的类) - 但它看起来更像是您想要指定一个绝对资源路径.

因此，如果您的 SqlSessionFactoryManager 位于包 kr.stocktalk.mybatis 中，它会尝试加载资源 kr.stocktalk.mybatis.kr.stocktalk.mybatis .mybatis-conf.xml.

您应该通过在开头添加斜杠来使资源路径成为绝对路径:

“/kr/stocktalk/mybatis/mybatis-conf.xml”
