背景
- 使用SpringBoot 运行一次性作业，用于初始化
- 问题：直接使用System.exit退出时，遇到异常：NoClassDefFoundError: ch/qos/logback/classic/spi/ThrowableProxy
异常信息

解决办法
- Spring 退出需要清理环境，使用SpringApplication.exit
- 参考代码
@Slf4j
@SpringBootApplication(exclude = {FreeMarkerAutoConfiguration.class, JacksonConverterAutoConfigurer.class})
@ComponentScan(value = {"XXXX"},
excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {JacksonConverterAutoConfigurer.class})
)
@MapperScan(basePackages = "XXXX.**.dao")
public class XXX {
public static void main(String[] args) {
try (ConfigurableApplicationContext context = SpringApplication.run(XXX.class, args)) {
XXX xxx = context.getBean(XXX.class);
xxx.init();
log.info("Init Over");
//System.exit(0);
exitApplication(context);
} catch (Exception e) {
log.error(ExceptionUtil.exceptionTrace(e));
System.exit(1);
}
}
private static void exitApplication(ConfigurableApplicationContext context) {
int exitCode = SpringApplication.exit(context, (ExitCodeGenerator) () -> 0);
System.exit(exitCode);
}
}
任务启动方式
java -Dloader.main=XXXTask -cp ./target/xxx.jar org.springframework.boot.loader.PropertiesLauncher --spring.config.location=xxx.properties
