我的Spring Boot应用程序正在运行，这是主类。
@SpringBootApplication
public class BwsApplication {
private ConfigClass config;
private static final Logger log = LoggerFactory.getLogger(Logs.class);
public BwsApplication(ConfigClass configClass) {
config = configClass;
}
public static void main(String[] args) {
SpringApplication.run(BwsApplication.class, args);
}
@PostConstruct
private void postConstruct() {
Connection con = null;
try {
con = config.getConnection();
} catch (SQLException e) {
log.error(e.toString());
}
QuartzApp qa = new QuartzApp(config);
qa.excecution();
}
}
配置完成后，我可以使用maven生成jar，并且可以正常运行，但是现在我需要生成WAR文件，因为该应用程序必须作为服务运行在tomcat服务器中。
这是我第一次使用Spring，因此我进行了研究，发现要生成war文件，我需要在pom.xml和主类中进行更改。
@SpringBootApplication
public class BwsApplication extends SpringBootServletInitializer {
private ConfigClass config;
private static final Logger log = LoggerFactory.getLogger(Logs.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(BwsApplication.class);
}
public BwsApplication(ConfigClass configClass) {
config = configClass;
}
public static void main(String[] args) {
SpringApplication.run(BwsApplication.class, args);
}
@PostConstruct
private void postConstruct() {
Connection con = null;
try {
con = config.getConnection();
} catch (SQLException e) {
log.error(e.toString());
}
QuartzApp qa = new QuartzApp(config);
qa.excecution();
}
}
带有更改的主类保持不变……我将其扩展为SpringBootServletInitializer并添加了configure方法。
我还对pom.xml进行了更改，他是完整的.xml

这些更改之后，当我尝试在intellij中运行应用程序时出现此错误

我遵循了提示，现在我可以在IDE中运行该应用程序，仅当尝试在tomcat中启动该应用程序时，才会构建war（程序包maven），但出现错误 失败-上下文路径[/bedelServer-0.0.1-SNAPSHOT]中的应用程序无法启动
