spring boot 打包

打成jar直接运行比较简单，这里特别说明的是打成war包，部署在外部的tomcat方式：

1、修改启动代码

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.web.support.SpringBootServletInitializer;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.stereotype.Controller;

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

@SpringBootApplication

@EnableAutoConfiguration

@ComponentScan("com.xx.xx")

@Controller

// mapper 接口类扫描包配置

public class Application extends SpringBootServletInitializer {

    @RequestMapping("/")

    String home() {

        return "index";

    }

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(Application.class);

    }

    public static void main(String[] args) throws Exception {

        SpringApplication.run(Application.class, args);

    }

}

2、修改pom.xml

<packaging>war</packaging>

去除一些可能冲突的配置项：

<dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-web</artifactId>

            <exclusions>

                <exclusion>

                    <groupId>com.fasterxml.jackson.core</groupId>

                    <artifactId>jackson-databind</artifactId>

                </exclusion>

                <exclusion>

                    <groupId>org.springframework.boot</groupId>

                    <artifactId>spring-boot-starter-tomcat</artifactId>

                </exclusion>

                <exclusion>

                    <groupId>org.slf4j</groupId>

                    <artifactId>log4j-over-slf4j</artifactId>

                </exclusion>

                <exclusion>

                    <groupId>org.springframework.boot</groupId>

                    <artifactId>spring-boot-starter-logging</artifactId>

                </exclusion>

            </exclusions>

            <version>1.5.1.RELEASE</version>

        </dependency>

增加servlet（可能不是必须的）

<dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>javax.servlet-api</artifactId>

            <version>4.0.0</version>

        </dependency>

tomcat外部依赖：

<dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-tomcat</artifactId>

            <version>1.4.7.RELEASE</version>

            <scope>provided</scope>

        </dependency>

war包名称：

<finalName>ROOT</finalName>

防止没有web.xml报错：

<plugin>

                <groupId>org.apache.maven.plugins</groupId>

                <artifactId>maven-war-plugin</artifactId>

                <version>2.4</version>

                <configuration>

                    <failOnMissingWebXml>false</failOnMissingWebXml>

                </configuration>

            </plugin>
