springboot项目既可以以jar运行，也可以做成war包放到服务器上，因为我的博客项目涉及到文件上传，所以按照jar的方式就不可行，需要部署到tomcat上，具体做法如下：
1. 修改pom.xml
1.1 将项目打包方式改为war：<packaging>war</packaging>
1.2 在spring-boot-starter-web的依赖中去除tomcat的包修改如下：
<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>
pom.xml
1.3 添加对tomcat容器的依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
pom.xml
1.4 移除spring-boot-maven-plugin插件，并增加maven-war-plugin插件：
<build>
<plugins>
<!-- <plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin> -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<warName>blog</warName>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
pom.xml
2. 修改App.java，使App继承自SpringBootServletInitializer，并重写SpringApplicationBuilder方法，代码如下：
package com.lvniao.blog; import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView; @Controller
@SpringBootApplication
public class App extends SpringBootServletInitializer {
@RequestMapping("/")
public ModelAndView index(Model model) {
model.addAttribute("hello", "Hello, World!");
return new ModelAndView("redirect:/home/");
} @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(App.class);
} public static void main( String[] args )
{
SpringApplication.run(App.class, args);
}
}
App.java
通过以上步骤后就可以通过maven来打包发布了。
