weblogic安装部署war包——windows

### weblogic安装部署war包——windows
#### 下载weblogic安装包
[csdn下载地址](https://download.csdn.net/download/luozhuang/10558048)
[官网下载地址](https://www.oracle.com/technetwork/middleware/weblogic/downloads/index.html)(这是快速安装版)
#### 安装weblgic
参考[WebLogicServer12.2.1.3服务器安装配置步骤详解](https://jingyan.baidu.com/article/4d58d54164eff49dd4e9c095.html)

**注意**
安装weblogic的jar包需要放置在jdk的home路径下，然后cd到该路径，在执行该jar。不然在执行java-jar命令时报错不是有效的 JDK Java 主目录。

#### weblogic部署普通war包
[weblogic使用方法]()
**注意**
这里不需要额外的配置，直接将打好的包上传即可。部署成功之后访问路径为**http://ip:端口号/上下文根**。上下文根一般指war包名称

#### weblogic部署springboot的war包
**注意，这里指的是纯springboot，不确定自己的项目部是不是纯springboot的时候，就用上面的方式**

[参考网址](https://blog.csdn.net/wonderful_life_mrchi/article/details/77915757)

修改项目的pom文件改为打war包，并排除到springboot-start-web中的tomcat，加上单独的tomcat,设置域为provided

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

**实现WebApplicationInitializer**,入口类继承SpringBootServletInitializer类并实现WebApplicationInitializer类，然后重写configure方法。直接复制改方法即可。最后打成war包部署。

package com.example;

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

@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer implements WebApplicationInitializer {
@Override
public SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}

#### 可能会出现的问题
##### 问题一 XXXX.<init>()

**解决方法**
**这是因为我的项目不是纯正的springboot项目，这是用Jhipster自动创建的。所以不能用weblogic部署springboot项目的方法来部署。这样就会画蛇添足，直接用原来的包即可**

##### 问题二 java.lang.ClassNotFoundException: com.querydsl.core.dml.UpdateClause

**解决方法**
**这是因为我们的项目引用了jpa相关的包没有被加载到，weblogic找不到这个包。需要把 `querydsl-core-4.1.4.jar`和`querydsl-jpa-4.1.4.jar`这两个包放到`D:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\lib`(weblogic的home目录下)。经反复测试，不需要像网上说的添加weblogic.xml或者其他设置。。**
