使用名称创建bean时出错：注入自动装配的依赖项失败，无法解析占位符

Question

I am trying to run my application (spring + hibernate) on a tomcat server but I am getting these errors. When I comment the property causing the errors, the next one triggers the same errors. I guess the properties are not recognized during initialization, I tried many solutions but none of them resolved the problem. Has anyone any idea to resolve this?

Answer 1

have you tried to rename your 'app.properties' file 'application.properties'? What is the path of this file ? It has to be under 'resources' directory if you don't want to manually configure its path.

Answer 2

Make sure your properties file resides in resources and you're copying it during compilation.

Also, the name needs to be application.properties or application-{profile}.properties. Read this for more info.

Configuration | Spring Framework Docs

If not, you can use @PropertySource to specify properties file if you're not naming it as per convention or external configurations.

Answer 3

I had app.properties and application.properties, I gathered these two files in application.properties and deleted the other but it does not change anything. The file is in "resources" directory and seems to be recognized by Intellij.

resources directory

I added this in the pom.xml

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

and the following line in WebConfig but it is still the same.

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

The application I'm trying to run is a fork of an application that used exactly the same properties, and that runs well..

Answer 4

Resolved it by adding this line in the pom

<filtering>true</filtering>

giving this

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