SpringBoot2學習筆記（七） 部署SpringBoot應用
阿新 • • 發佈：2018-12-26
SpringBoot預設使用jar方式執行
1.以jar檔案方式
1）使用jar方式打包
a.在pom.xml中匯入相應外掛
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin b.在工程目錄下使用maven打包
1.使用命令：mvn package 打包
或者
2.使用idea外掛打包
控制檯成功結果：
[INFO]
[INFO] --- maven-jar-plugin:3.0.2:jar (default-jar) @ spring-boot-04-servlet01 ---
[INFO] Building jar: E:\基礎專案\Java_Project\java_project_idea\springboot-demo\spring-boot-04-servlet\spring 2)執行jar檔案
使用java -jar xxx 方式執行jar檔案
java -jar spring-boot-04-servlet01-0.0.1-SNAPSHOT.jar
2.以war檔案方式，使用外部Servlet容器執行
1.嵌入式Servlet容器：
應用打成可執行的jar
優點：簡單、便攜；
缺點：預設不支援JSP、優化定製比較複雜
2.外接的Servlet容器：
外面安裝Tomcat---應用war包的方式打包
3.基本的web目錄
4.idea生成webapp
1.手動建立的方式生成
2.使用自動生成
步驟圖示：
圖2步驟3 具體操作
圖2步驟4具體操作
xxx\src\main\webapp\WEB-INF\web.xml
5.idea使用外部tomcat
之後點選OK，即部署完畢
點選run啟動即可
啟動結果：
6.使用idea部署遇到的坑
1.Tomcat報錯：此時不應有 =2048”“
錯誤原因：2048周圍多了引號，開啟catalina.bat檔案將包含2048的語句的引號全部刪除
此時不應有 =2048”“
2.idea配置預設JDK
在專案下 File
3.缺少配置

原因：未配置資料來源
使用了mysql + jdbc模組
我覺得是由於我們使用了外部的tomcat容器所以內嵌的tomcat容器就失效了，所以資料來源也就失效了
解決辦法：
1.註釋掉pom檔案內的jdbc引用
2.在主函式加上@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
3.配置新的資料來源
放棄使用預設的資料來源，使用新的資料來源
例如：更換資料來源為Druid
方法1：
步驟：
1.pom檔案中引入Druid依賴
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.10</version>
</dependency>
@Configuration
@ConfigurationProperties(prefix = "spring.datasource")
public class DruidConfig {
private String url;
private String username;
private String password;
private String driverClassName;
public String getUrl() {
return url;
}
public void setDataUrl(String url) {
this.url = url;
}
public String getUsername() {
return username;
}
public void setDataUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setDataPassword(String password) {
this.password = password;
}
public String getDriverClassName() {
return driverClassName;
}
public void setDriverClassName(String driverClassName) {
this.driverClassName = driverClassName;
}
//配置新的資料來源
@Bean
public DataSource druidDatasource(){
DruidDataSource dataSource = new DruidDataSource();
dataSource.setUrl(this.url);
dataSource.setUsername(this.username);
dataSource.setPassword(this.password);
dataSource.setDriverClassName(this.driverClassName);
return dataSource;
}
}或者
@Configuration
public class DruidConfig {
@Autowired
private Environment env;
//配置新的資料來源
@Bean
public DataSource dataSource() {
DruidDataSource dataSource = new DruidDataSource();
dataSource.setUrl(env.getProperty("spring.datasource.url"));
dataSource.setUsername(env.getProperty("spring.datasource.username"));
dataSource.setPassword(env.getProperty("spring.datasource.password"));
dataSource.setDriverClassName(env.getProperty("spring.datasource.driver-class-name"));
return dataSource;
}
}
3.在application.xml或者application.yml上配置基本資料來源資訊
spring.datasource.data-username=root
spring.datasource.data-password=root
spring.datasource.data-url=jdbc:mysql://localhost:3306/test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver4.執行tomcat，成功啟動，資料來源為druid
方法2：
在配置檔案application.properties/application.yml中配置資料來源
可以使用spring.datasource.type指定自定義的資料來源型別；
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
