一、jar包的制作
1、maven工程引入下列三个依赖
<dependencies>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.20.RELEASE</version>
<scope>provided</scope>
<optional>true</optional>
</dependency>
<!-- 使用SLF4J和LogBack作为日志 -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>${slf4j.version}</version>
<scope>provided</scope>
<optional>true</optional>
</dependency>
</dependencies>
2、写三个Java文件 和 相应资源包（vue+element）
3、写index.html ，可直接引用本地资源也可cdn 引入，正常编写网页
===================
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
</head>
<body>
<div id="app">
<el-button @click="visible = true">Button</el-button>
<el-dialog :visible.sync="visible" title="Hello world">
<p>Try Element</p>
</el-dialog>
</div>
</body>
<script src="https://unpkg.com/vue/dist/vue.js"></script>
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
<script>
new Vue({
el: '#app',
data: function() {
return { visible: false }
}
})
</script>
</html>
===================
4、InitListener 初始化文件，执行相应初始化动作，可不加
package com.juncheng.syc.listener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class InitListener implements ServletContextListener {
private static final Logger log = LoggerFactory.getLogger(InitListener.class);
public void contextInitialized(ServletContextEvent servletContextEvent) {
log.info("=====================添加依赖开始运行！================================");
}
public void contextDestroyed(ServletContextEvent servletContextEvent) {
}
}
5、MvcConfig配置文件，自动装配bean
package com.juncheng.syc.config;
import com.juncheng.syc.listener.InitListener;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@EnableWebMvc
@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
@Bean
public InitListener thisListener(){
return new InitListener();
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/syc/**")
.addResourceLocations("classpath:/ui/");
}
}
6、ThisApi 自定义注解类，并引入MvcConfig.class
package com.juncheng.syc.annotation;
import com.juncheng.syc.config.MvcConfig;
import org.springframework.context.annotation.Import;
import java.lang.annotation.*;
@Target({ElementType.TYPE,ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Import(MvcConfig.class)
public @interface ThisApi {
}
7、生成jar包
二、jar包本地引入，并执行
1、新建springboot项目，引入web 和 thymeleaf ，正常执行，并做一个主页进行测试
2、本地引入jar包，在resources下新建lib ,并复制jar包
<dependency>
<groupId>springVueElm</groupId>
<artifactId>springVueElm</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/src/main/resources/lib/springVueElm-1.0-SNAPSHOT.jar</systemPath>
</dependency>
3、在启动类上，填写注解
4、正常执行，并访问jar中Configuration 中addResourceHandlers 配置的访问路径，就可以访问jar中的静态页面了
三、本地jar引入后打包注意事项
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<!--把本地jar包也引入进去-->
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
<!--在这里修改版本-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.4.3</version>
</plugin>
</plugins>
</build>
四、获取相关设置（简单通信）
1、InitListener
···
package com.juncheng.syc.listener;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
public class InitListener implements ServletContextListener {
private static final Logger log = LoggerFactory.getLogger(InitListener.class);
@Autowired
private Environment env;
public void contextInitialized(ServletContextEvent servletContextEvent) {
//获取属相相关设置
String status = env.getProperty("thisApi.status");
log.info("=====================添加依赖开始运行！================================");
log.info("=====================thisApi.status:["+status+"]==============================");
}
public void contextDestroyed(ServletContextEvent servletContextEvent) {
}
}
···
2、设置 application.properties
