SpringBoot項目部署到WebLogic

最近公司需要把springboot的項目發佈到weblogic上去運行，其中搞出很多問題，現在把解決方案記錄一下。

修改SpringBoot啓動類

主要是繼承extends SpringBootServletInitializer 類，實現 WebApplicationInitializer接口，重寫方法protected SpringApplicationBuilder configure(SpringApplicationBuilder builder)

package com.dowhere.webtest;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.WebApplicationInitializer;

@SpringBootApplication
public class WebtestApplication extends SpringBootServletInitializer implements WebApplicationInitializer {


    /**
     * 重寫方法configure
     * @param builder
     * @return
     */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(WebtestApplication.class);
    }

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

}

修改pom文件

修改打包方式war，同時添加tomcat的支持

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                <exclusion>

            </exclusions>

        </dependency>
    </dependencies>

    <build>

            </plugin>
        </plugins>
    </build>

</project>

使用Logback

如果在項目中使用了Logback，需要告訴WebLogic打包版本，而不是服務器預先安裝的版本。
可以通過添加WEB-INF/weblogic.xml具有內容如下：

<?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
        https://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd
        http://xmlns.oracle.com/weblogic/weblogic-web-app
        https://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:prefer-application-packages>
    </wls:container-descriptor>
</wls:weblogic-web-app>
