【Spring Boot学习之八】发布打包

环境
　　eclipse 4.7
　　jdk 1.8
　　Spring Boot 1.5.2

一、打jar类型
1、指定主程序入口,否则运行报错：没有主清单属性
pom.xml:

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <maimClass>com.wjy.APP</maimClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

2、打包

2、运行
java -jar springboot-helloworld-0.0.1-SNAPSHOT.jar

二、打war类型

如果要使打出来的war包可以使用命令 java -jar运行，需要将静态文件（html/jsp）一并打入可执行文件
1、pom.xml
这是一个整合jsp的web应用

<project xmlns="http://maven.apache.org/POM/4.0.0"

            <scope>provided</scope>
        </dependency>
    </dependencies>

    <build>
        <resources>
            <resource>
                <!--注意必须要放在此目录下才能被访问到 -->
                <directory>${basedir}/src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>

            </resource>
            <resource>
                <directory>${basedir}/src/main/resources</directory>

                    <target>1.8</target>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.springframework.boot</groupId>

                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

2、打包

mvn package

3、运行

java -jar spring-boot-jsp-0.0.1-SNAPSHOT.war

三、Spring Boot web应用打成WAR包部署到外部TOMCAT

1、pom.xml
(1)将打包方式修改为war

<packaging>war</packaging>

(2)移除tomcat依赖或者将tomcat依赖scope改为provide

<dependency>
　　<groupId>org.springframework.boot</groupId>
　　　　<artifactId>spring-boot-starter-web</artifactId>
　　　　<!-- 移除嵌入式tomcat插件 -->
　　　　<exclusions>
　　　　　　<exclusion>
　　　　　　　　<groupId>org.springframework.boot</groupId>
　　　　　　　　<artifactId>spring-boot-starter-tomcat</artifactId>
　　　　　　</exclusion>
　　　　</exclusions>
</dependency>

或者

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

2、继承SpringBootServletInitializer

继承org.springframework.boot.web.servlet.support.SpringBootServletInitializer，实现configure方法：
为什么继承该类，SpringBootServletInitializer就是原有的web.xml文件的替代。

(1)方式一，启动类继承SpringBootServletInitializer实现configure：

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

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

(2)方式二，新增加一个类继承SpringBootServletInitializer实现configure：

public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        //此处的Application.class为带有@SpringBootApplication注解的启动类
        return builder.sources(Application.class);
    }

}

3、注意事项：
(1)使用外部Tomcat部署访问的时候，application.properties(或者application.yml)中配置的
server.port=
server.servlet.context-path=
将失效；

(2)为了防止应用上下文所导致的项目访问资源加载不到的问题，建议pom.xml文件中<build></build>标签下添加<finalName></finalName>标签

<build>
　　<finalName>${project.artifactId}</finalName>
</build>

(3)spring boot只支持tomcat 8.5 以上版本，如果外部tomcat版本过低，需要在pom.xml里指定低版本的tomcat

<properties>
    <tomcat.version>7.0.47</tomcat.version>
</properties>

4、示例：

SpringBoot整合jsp web应用使用外置容器运行示例：

(1)pom.xml

                </configuration>
            </plugin>
        </plugins>
        <finalName>${project.artifactId}</finalName>
    </build>
</project>

(2)Controller

package com.wjy.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

    @RequestMapping("/index")
    public String index() {
        return "index";
    }
}

(3)jsp

<%@ page language="java" contentType="text/html; UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
Spring Boot 整合 JSP
</body>
</html>

(4)启动类

package com.wjy;

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

@SpringBootApplication
public class App extends SpringBootServletInitializer{

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(App.class);
    }
}

打包、部署到tomcat ，并启动tomcat:
