注册 @Configuration 标识的类，spring 读取配置文件的时候该类会被自动装载

package cn.com.receive; import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class ApplicationInitialize {        @Value("${tms.terminal.search:200}")    private int search;    @Value("${tms.terminal.monitor:15}")    private int monitor;    @Value("${tms.terminal.signkey:POI:}")    private String signkey;        @Value("${tms.terminal.queueName:gps}")    private String queueName;        @Value("${tms.terminal.exchangeName:tms}")    private String exchangeName;        @Value("${tms.terminal.routingKey:tms}")    private String routingKey;        @Bean    public ConsumerService consumerService() {        try {            ConsumerService consumerService = new ConsumerService(search,monitor,signkey,queueName,exchangeName,routingKey);            return consumerService;        } catch (Exception e) {            // TODO: handle exception            throw e;        }    }}
