新建获取上下文工具类SpringContextUtil
package com.frank.lmsg.base.utils;
import org.springframework.context.ApplicationContext;
/**

public class SpringContextUtil {
private static ApplicationContext applicationContext;
//获取上下文
public static ApplicationContext getApplicationContext() {
return applicationContext;
}
//设置上下文
public static void setApplicationContext(ApplicationContext applicationContext) {
SpringContextUtil.applicationContext = applicationContext;
}
//通过名字获取上下文中的bean
public static Object getBean(String name){
return applicationContext.getBean(name);
}
//通过类型获取上下文中的bean
public static Object getBean(Class<?> requiredType){
return applicationContext.getBean(requiredType);
}
}
在Application里面初始化上下文
package com.frank.lmsg;
import com.frank.lmsg.base.utils.SpringContextUtil;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
@MapperScan("com.frank.lmsg.mybatis.mapper")
public class LmsgApplication {
public static void main(String[] args) {
ApplicationContext app = SpringApplication.run(LmsgApplication.class, args);
SpringContextUtil.setApplicationContext(app);
}
}
获取上下文
ApplicationContext app = SpringContextUtil.getApplicationContext();
