将Spring Boot部署到Weblogic时的NoSuchMethodError

Question

I've got a Spring Boot application running fine locally via the built in tomcat server but I'm having issues deploying it as a war file in Weblogic 12.2. I've followed the "85.1 Create a deployable war file" section of the Spring Boot reference guide to build the war file, created a new Weblogic managed server to host it and followed the deployment install steps on Weblogic but get the below exception when clicking start "servicing all requests" on the deployment. Any suggestions?

Dependencies section of build.gradle:

dependencies {
    compile fileTree(dir: 'lib', include: '*.jar')
    compile(
        'org.springframework.boot:spring-boot-starter-web:1.5.8.RELEASE',
        'org.springframework.boot:spring-boot-devtools',
        'org.springframework.boot:spring-boot-starter-jdbc',
        'org.springframework.boot:spring-boot-starter-data-jpa',
        'com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.9.2',
        'org.springframework.boot:spring-boot-starter-security',
        'javax.servlet:javax.servlet-api:3.1.0'
    )
    testCompile(
        'org.springframework.security:spring-security-test',
        'org.springframework.boot:spring-boot-starter-test'
    )
    providedRuntime (
        'org.springframework.boot:spring-boot-starter-tomcat'
    )
}

Exception received from Weblogic when clicking start "servicing all requests":

Caused By: java.lang.NoSuchMethodError: org.springframework.web.context.support.StandardServletEnvironment.initPropertySources(Ljavax/servlet/ServletContext;Ljavax/servlet/ServletConfig;)V

        Loads more weblogic errors here.

My application entry point appears to be okay:

@SpringBootApplication
public class Application extends SpringBootServletInitializer implements WebApplicationInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Add a weblogic deployment descriptor as said in spring-docs . Create a file named weblogic.xml and add this code to the xml.

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app
    xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd
        http://xmlns.oracle.com/weblogic/weblogic-web-app
        http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd">
    <wls:container-descriptor>
        <wls:prefer-application-packages>
            <wls:package-name>org.slf4j</wls:package-name>
            <wls:package-name>org.springframework.*</wls:package-name>
        </wls:prefer-application-packages>
    </wls:container-descriptor>
</wls:weblogic-web-app>

Now put the weblogic.xml file into WEB-INF folder so that full path will be WEB-INF/weblogic.xml .

Update: Add a empty dispatcher-servlet.xml to WEB-INF/ folder.

dispatcher-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>

And your build.gradle add dependency

org.springframework.boot:spring-boot-starter-web

Also remove

providedRuntime (
    'org.springframework.boot:spring-boot-starter-tomcat'
)
