通过Spring容器拿到bean,不通过依赖注入,SpringBoot框架
1.自定义bean
package com.baosight.jhy.pc.cs.domain; public class Teacher { private String name; private String address; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
2.注册bean到Spring容器
package com.baosight.jhy.pc.cs.excel; import com.baosight.jhy.pc.cs.domain.Teacher; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class ExcelConfig { @Bean public Teacher teacher() { Teacher teacher = new Teacher(); teacher.setName("无双剑姬"); teacher.setAddress("恕瑞玛"); teacher.setAge(6300); return teacher; } }
3.Spring容器获取
package com.baosight.jhy.pc.cs.excel; import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; @Component public class SpringContextUtils implements ApplicationContextAware { private static ApplicationContext context; @Override public void setApplicationContext(ApplicationContext context) throws BeansException { SpringContextUtils.context = context; } public static ApplicationContext getContext() { return context; } }
4.获取bean
Teacher bean = SpringContextUtils.getContext().getBean(Teacher.class); bean.getName();
