SpringBoot中jar打包并部署到Tomcat

更新時間：2021年05月21日 09:38:58 作者：張起靈-小哥

最近做了一個SpringBoot項目，今天介紹一下SpringBoot中jar打包并部署到Tomcat，具有一定的參考價值，感興趣的小伙伴們可以參考一下

1.詳細(xì)步驟

首先在pom.xml文件中做一些修改：

之前打war包需要修改打包方式，這次不需要了，因為默認(rèn)就是 jar 包指定最終打成jar包的名稱手動指定 resources 文件夾編譯打包的路徑添加SpringBoot內(nèi)嵌Tomcat解析jsp的依賴（僅僅是為這個實例而添加）

    </properties>
 
    <dependencies>
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>
 
        <dependency>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
 
    </dependencies>
 
    <build>
        <finalName>SpringBootJar</finalName>
 
        <resources>
            <resource>
                <directory>src/main/webapp</directory>
                <targetPath>META-INF/resources</targetPath>
                <includes>
                    <include>*.*</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.*</include>
                </includes>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>1.4.2.RELEASE</version>
            </plugin>
        </plugins>
    </build>
 
</project>

之后寫一個控制層，UserController

package com.songzihao.springboot.controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
 
import java.util.HashMap;
import java.util.Map;
 
/**
 *
 */
@Controller
public class UserController {
 
    @RequestMapping(value = "/user/detail")
    public @ResponseBody Object userDetail() {
        Map<String,Object> map=new HashMap<>();
        map.put("id",1001);
        map.put("username","張起靈");
        return map;
    }
 
    @RequestMapping(value = "/user/page/detail")
    public String userPageDetail(Model model) {
        model.addAttribute("id",1001);
        model.addAttribute("username","小哥");
        return "userDetail";
    }
 
}

在核心配置文件中，配置內(nèi)嵌Tomcat的端口號、上下文根，以及視圖解析器。

server.port=9090
server.servlet.context-path=/
 
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

然后寫一個控制層中對應(yīng)的jsp頁面，用做模擬測試。

<%@ page contentType="text/html;charset=utf-8" language="java" %>
<html>
<head>
    <title>$</title>
</head>
<body>
    <h3>用戶編號：${id}</h3>
    <h3>用戶姓名：${username}</h3>
</body>
</html>

最后是SpringBoot項目的入口類。

package com.songzihao.springboot;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class Application {
 
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
 
}

1.1 在IDEA中啟動測試
