SpringBoot打war包部署

項目名稱：036-springboot-war

創建SpringBoot Web項目

1.創建一個新的Module

2.在pom.xml文件中配置內嵌Tomcat對jsp的解析包

<!--SpringBoot項目內嵌tomcat對jsp的解析包-->
<dependency>
   <groupId>org.apache.tomcat.embed</groupId>
   <artifactId>tomcat-embed-jasper</artifactId>
</dependency>

3.在pom.xml文件中配置jsp文件解析目錄

<!--
    SpringBoot要求jsp文件必須編譯到指定的META-INF/resources目錄下，否則不能訪問
-->
<resources>
    <resource>
        <!--源文件位置-->
        <directory>src/main/webapp</directory>
        <!--指定編譯到META-INF/resources目錄下，該目錄不能隨便編寫-->
        <targetPath>META-INF/resources</targetPath>
        <!--指定包含文件-->
        <includes>
            <include>**/*.*</include>
        </includes>
    </resource>
</resources>

4.創建webapp并指定為web資源文件夾

5.在application.properties配置文件中配置內嵌Tomcat端口號及上下文根和jsp的前后綴

#設置內嵌Tomcat端口號
server.port=9090
#設置應用的上下文根
server.servlet.context-path=/036-springboot-war


#設置jsp的前/后綴
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp

6.創建IndexController提供方法分別返回字符串及跳轉頁面

package com.abc.springboot.web;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;

/**
 * ClassName:IndexController
 * Package:com.abc.springboot.web
 * Description:

 */
@Controller
public class IndexController {

    @GetMapping(value = "/springboot/index")
    public String index(HttpServletRequest request, Model model) {
        model.addAttribute("data","Hello SpringBoot JSP");
        return "index";
    }

    @GetMapping(value = "/springboot/data")
    public @ResponseBody Object data() {
        return "SpringBoot Data ";
    }

}

7.在src/main/webapp目錄下創建index.jsp

8.瀏覽器輸入地址訪問測試

打War包

1.程序入口類需擴展繼承 SpringBootServletInitializer類并覆蓋configure方法

@SpringBootApplication
public class Application extends SpringBootServletInitializer{
   public static void main(String[] args) {
      SpringApplication.run(Application.class, args);
   }
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
//參數為當前Spring Boot啟動類Application.class
      return builder.sources(Application.class);
   }
}

2.在 pom.xml中添加(修改)打包方式為war 

<packaging>war</packaging>

3.在 pom.xml中配置springboot打包的插件(默認自動加)

<!--SpringBoot 的打包插件-->
<plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
</plugin>

4.在pom.xml中配置將配置文件編譯到類路徑

	
<!--mybatis的mapper.xml-->
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.xml</include>
        </includes>
    </resource>
    <!--src/main/resources下的所有配置文件編譯到classes下面去-->
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.*</include>
        </includes>
    </resource>
    <resource>
        <!--源文件位置-->
        <directory>src/main/webapp</directory>
        <!--編譯到META-INF/resources，該目錄不能隨便寫-->
        <targetPath>META-INF/resources</targetPath>
        <includes>
            <!--要把哪些文件編譯過去，**表示webapp目錄及子目錄，*.*表示所有-->
            <include>**/*.*</include>
        </includes>
    </resource>

5.在pom.xml的build標簽下通過finalName指定打war包的名字

<!--指定打war包的名字-->
<finalName>036-springboot-war</finalName>

6.通過Maven package命令打war包到target目錄下

部署到Tomcat服務器上測試運行

1.將target目錄下生成的war包拷貝到tomcat的webapps目錄，并啟動tomcat

2.通過瀏覽器訪問
