本文主要是介绍springboot 项目打成war包部署到tomcat下,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
一.打包方式的概述
1.1、ide启动
1.2 jar包方式
maven插件:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
如果没有加,则执行jar包 ,报错如下
java -jar spring-boot-demo-0.0.1-SNAPSHOT.jar
no main manifest attribute, in spring-boot-demo-0.0.1-SNAPSHOT.jar
如果有安装maven 用 mvn spring-boot:run
1.3 打成war的流程配置
1.在pom.xml中将打包形式 jar 修改为war <packaging>war</packaging>
2.构建项目名称 <finalName>xdclass_springboot</finalName>
3.tocmat下载 https://tomcat.apache.org/download-90.cgi
4.修改启动类
public class XdclassApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(XdclassApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(XdclassApplication.class, args);
}
}
4)打包项目,启动tomcat
二.新建项目 springboot的war包部署到tomcat下
2.1 配置pom文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.3.3.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.ljf.spt.war.deployment</groupId><artifactId>demo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name>12-spt-war-deployment</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope><exclusions><exclusion><groupId>org.junit.vintage</groupId><artifactId>junit-vintage-engine</artifactId></exclusion></exclusions></dependency></dependencies><build><!-- 打包的项目名称 --><finalName>12-spt-war-deployment</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>
2.2 controller
package com.ljf.spt.war.deployment.demo.controller;import com.ljf.spt.war.deployment.demo.model.JsonData;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;/*** @ClassName: UserController* @Description: TODO* @Author: liujianfu* @Date: 2020/09/08 08:31:37 * @Version: V1.0**/
@RestController
public class UserController {/*** 功能描述:微信支付回调接口* @param msg 支付信息* @return*/@GetMapping("order")public Object order(String msg){return JsonData.buildSuccess("beijing","ok");}
}
2.3 domain
package com.ljf.spt.war.deployment.demo.model;import java.io.Serializable;/*** @ClassName: JsonData* @Description: TODO* @Author: liujianfu* @Date: 2020/09/08 09:04:49 * @Version: V1.0**/
public class JsonData implements Serializable {/****/private static final long serialVersionUID = 1L;private Integer code; // 状态码 0 表示成功,1表示处理中,-1表示失败private Object data; // 数据private String msg;// 描述public JsonData() {}public JsonData(Integer code, Object data, String msg) {this.code = code;this.data = data;this.msg = msg;}// 成功,传入数据public static JsonData buildSuccess(String name,String msg) {return new JsonData(0, name, msg);}// 成功,传入数据public static JsonData buildSuccess(Object data) {return new JsonData(0, data, null);}// 失败,传入描述信息public static JsonData buildError(String msg) {return new JsonData(-1, null, msg);}// 失败,传入描述信息,状态码public static JsonData buildError(String msg, Integer code) {return new JsonData(code, null, msg);}// 成功,传入数据,及描述信息public static JsonData buildSuccess(Object data, String msg) {return new JsonData(0, data, msg);}// 成功,传入数据,及状态码public static JsonData buildSuccess(Object data, int code) {return new JsonData(code, data, null);}public Integer getCode() {return code;}public void setCode(Integer code) {this.code = code;}public Object getData() {return data;}public void setData(Object data) {this.data = data;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}@Overridepublic String toString() {return "JsonData [code=" + code + ", data=" + data + ", msg=" + msg+ "]";}
}
2.4 users
package com.ljf.spt.war.deployment.demo.model;import java.util.Date;/*** @ClassName: User* @Description: TODO* @Author: liujianfu* @Date: 2020/09/08 08:51:33 * @Version: V1.0**/
public class User {private int age;private String pwd;private String phone;private Date createTime;public Date getCreateTime() {return createTime;}public void setCreateTime(Date createTime) {this.createTime = createTime;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}public User() {super();}public User(int age, String pwd, String phone, Date createTime) {super();this.age = age;this.pwd = pwd;this.phone = phone;this.createTime = createTime;}}
2.5 utils
package com.ljf.spt.war.deployment.demo.utils;import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.util.StringUtils;import java.io.IOException;/*** @ClassName: JsonUtils* @Description: TODO* @Author: liujianfu* @Date: 2020/09/08 08:33:25 * @Version: V1.0**/
public class JsonUtils {private static ObjectMapper objectMapper = new ObjectMapper();//对象转字符串public static <T> String obj2String(T obj){if (obj == null){return null;}try {return obj instanceof String ? (String) obj : objectMapper.writeValueAsString(obj);} catch (Exception e) {e.printStackTrace();return null;}}//字符串转对象public static <T> T string2Obj(String str,Class<T> clazz){if (StringUtils.isEmpty(str) || clazz == null){return null;}try {return clazz.equals(String.class)? (T) str :objectMapper.readValue(str,clazz);} catch (IOException e) {e.printStackTrace();return null;}}
}
2.6 启动类
package com.ljf.spt.war.deployment.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;@SpringBootApplication
public class Application extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(Application.class);}public static void main(String[] args) throws Exception {SpringApplication.run(Application.class, args);System.out.println("启动成功!!!");}}
2.7 打war包
2.8 部署到tomcat下
启动startup.bat脚本
2.9 页面访问
2.10 遗留的坑
1.打成war包,部署到tomcat8.5.6 下,进行启动,报jackson的2.10.3与tomcat8不兼容。
2.换成tomcat9还是不行,
3.目前不影响项目的使用,只是启动报错.....求解决???
