创建名称为bean的错误：自动连接的依赖项注入失败，无法解析占位符

标签： java spring spring-boot

我试图在tomcat服务器上运行我的应用程序（spring + hibernate），但出现这些错误。当我注释导致错误的属性时，下一个将触发相同的错误。 我猜这些属性在初始化期间无法识别，我尝试了许多解决方案，但没有一个解决了问题。有任何人有解决这个问题的想法吗？

4 个答案:

答案 0 :(得分：0)

您是否尝试过将“ app.properties”文件重命名为“ application.properties”？ 该文件的路径是什么？如果您不想手动配置其路径，则它必须位于“资源”目录下。

答案 1 :(得分：0)

确保属性文件位于资源中，并且在编译过程中正在复制它。

此外，名称也必须是application.properties或application- {profile} .properties。阅读此以获得更多信息。

Configuration | Spring Framework Docs

如果没有，则可以使用@PropertySource来指定属性文件（如果不按照约定或外部配置命名）。

答案 2 :(得分：0)

我有app.properties和application.properties，我在application.properties中收集了这两个文件，并删除了另一个，但它没有任何改变。该文件位于“资源”目录中，似乎可以被Intellij识别。

resources directory

我在pom.xml中添加了它

<build>
    <resources>     
        <resource>
            <directory>src/main/resources</directory>
            <includes>                      
                <include>**/*.properties</include>                  
            </includes>
        </resource>            
    </resources>
</build>

和WebConfig中的下一行，但仍然相同。

@PropertySource("classpath:/application.properties")

我要运行的应用程序是使用完全相同的属性并且运行良好的应用程序的分支。

答案 3 :(得分：0)

通过在pom中添加此行来解决

<filtering>true</filtering>

为此

<build>
    <resources>     
        <resource>
            <filtering>true</filtering>
            <directory>src/main/resources</directory>
            <includes>                      
                <include>**/*.properties</include>                  
            </includes>
        </resource>            
    </resources>
</build>
