SpringBoot通过ApplicationArguments获取args
如果你需要获取通过SpringApplication.run(…)传输过来的arguments,可以直接注入一个ApplicationArguments即可实现,如下面这个例子:
@Service public class ApplicationArgumentService { private final ApplicationArguments applicationArguments; @Autowired public ApplicationArgumentService(ApplicationArguments applicationArguments) { this.applicationArguments = applicationArguments; for (String sourceArg : applicationArguments.getSourceArgs()) { System.out.println(sourceArg); } for (String optionName : applicationArguments.getOptionNames()) { System.out.println(optionName + " = " + applicationArguments.getOptionValues(optionName)); } } }
当然,要注意的是SpringBoot的启动类中,在执行run方法的时候参数不能为空(标红部分):
@SpringBootApplication public class SpringBootTestApplication { public static void main(String[] args) { SpringApplication.run(SpringBootTestApplication.class, args); } }
