手动启动spring部分组件方法

1.加载配置文件

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() throws FileNotFoundException {

        try {
            PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
            YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
            yaml.setResources(new ClassPathResource("application.yaml"));
            configurer.setProperties(Objects.requireNonNull(yaml.getObject()));
            return configurer;
        } catch (IllegalStateException e) {
            Throwable cause = e.getCause();
            if (cause instanceof FileNotFoundException){
                throw (FileNotFoundException) e.getCause();
            }
            throw e;
        }
    }

2.启动

@ComponentScan(basePackages = "lab.service")
@EnableAutoConfiguration
public class BandJob {

    public static void main(String[] args) {
        AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(BandJob.class,LoadConfig.class);
        CalculateResultHandlerService calculateResultHandlerService = applicationContext.getBean(CalculateResultHandlerService.class);
        calculateResultHandlerService.handlerBand();
        System.exit(0);
    }

}

java本身不适合写脚本，多是作为服务器启动的，但是如果能够让脚本形式的java使用spring的组件，那么就可以复用很多东西，减少一些重复的代码

这里没引入spring日志组件，因此手动写logback.xml控制日志输出
logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
<!--    <property name="LOG_HOME" value="D:\log" />-->
    <!-- 控制台输出 -->
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
            <pattern>%white(%d{yyyy-MM-dd HH:mm:ss.SSS}) [%thread] %highlight(%-5level) %logger{50} - %msg%n</pattern>
        </encoder>
    </appender>
    <!-- 按照每天生成日志文件 -->
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!--        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">-->
<!--            &lt;!&ndash;日志文件输出的文件名&ndash;&gt;-->
<!--            <FileNamePattern>${LOG_HOME}/Main.log.%d{yyyy-MM-dd}.log</FileNamePattern>-->
<!--            &lt;!&ndash;日志文件保留天数&ndash;&gt;-->
<!--            <MaxHistory>30</MaxHistory>-->
<!--        </rollingPolicy>-->
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
            <pattern>%white(%d{yyyy-MM-dd HH:mm:ss.SSS}) %highlight(%lsn) [%thread] %-5level %logger{50} - %msg%n</pattern>
            <charset>utf8</charset>
        </encoder>
        <!--日志文件最大的大小-->
        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>10MB</MaxFileSize>
        </triggeringPolicy>
    </appender>

    <!-- 日志输出级别 -->
    <root level="INFO">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

或者也可以直接使用Spring的配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />
</configuration>
