• OS version: __mac os 10.13.4 ___
• JDK version: 8_
• SpringBoot version: 2.0.0.RELEASE
• SpringCloud version: Finchley.M8

Whats the problem?

1， pom

        <dependency>
            <groupId>com.github.dozermapper</groupId>
            <artifactId>dozer-core</artifactId>
            <version>6.4.0</version>
        </dependency>
        <dependency>

            <artifactId>dozer-spring-boot-starter</artifactId>
            <version>6.4.0</version>
        </dependency>

2 application.yml，

dozer:
  mappingFiles: classpath*:dozer/*.dozer.xml

3, mapping file :

 src/main/resources/dozer/global.dozer.xml

The line that is throwing the error, is a spring class:

• https://github.com/DozerMapper/dozer/blob/master/dozer-integrations/dozer-spring-support/dozer-spring4/src/main/java/com/github/dozermapper/spring/DozerBeanMapperFactoryBean.java#L81

Not sure how its a dozer problem...

[garethahealy]

We also have tests using classpath lookup, which dont fail:

• https://github.com/DozerMapper/dozer/blob/master/dozer-integrations/dozer-spring-support/dozer-spring4/src/test/resources/applicationContext.xml#L32

[garethahealy]

@zuihou ; if you still have this issue, please provide a github repo with a junit test showing the problem.

[tryIdea]

I also have the problem.why

[garethahealy]

@tryIdea ; as the comment above says, please provide a github repo with a junit test showing the issue.

[tryIdea]

@garethahealy github repo: dozer-test

[garethahealy]

@tryIdea ; i am unable to build your example. get the following error:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.1.1.RELEASE:repackage (repackage) on project dozer-test-domain: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.1.1.RELEASE:repackage failed: Unable to find main class

[tryIdea]

@garethahealy Code has been updated

[xrogzu]

@garethahealy ServletContext resource cannot load "classpath*",the reson maybe the interface Resource of Resource[] mappingFiles,injected by springboot, now only support dozer.mappingFiles=classpath:dozer/global-configuration.xml,classpath:dozer/user-mapping.xml

[ulquio]

Hello
Same problem here
The path is correct but still got FileNotFoundException

@zuihou Did you find a solution please ? I am using spring boot as well

Thank you

Thank you

dozer:
mappingFiles:
- classpath:dozer/global.dozer.xml # ok
- classpath:dozer/xxx.dozer.xml # ok
#mappingFiles: classpath*:dozer/*.dozer.xml # cannot use *

[garethahealy]

@kazuki43zoo ; if you are able, can you have a look at this please

[kazuki43zoo]

@garethahealy @zuihou

I've investigated this behavior and I found that it occurred since Spring Boot 2.x (1.5.x work fine). I think this issue's cause belong the Spring Boot project. Hence I've created the spring-projects/spring-boot#15835.

you can use this way to reduce it error

1. create applicationContext.xml to assign where is your dozer xml location

        <!--this value is your dozer xml -->

    </bean>

</beans>

2. config your application.yml

server:
  port: 80

spring:
  config:
    location: classpath:applicationContext.xml
