Spring中的方法

@ImportResource：导入Spring的配置文件，让配置文件里面的内容生效；

Spring Boot里面没有Spring的配置文件，自己编写的配置文件，也不能自动识别；

想让Spring的配置文件生效，加载@ImportResource标注配置类

项目结构如下：

程序运行截图如下：

对应的源码为：

源码如下：

Dog.java

package com.sourceinport.demo.bean;public class Dog {private String name;private Integer age;@Overridepublic String toString() {return "Dog{" +"name='" + name + '\'' +", age=" + age +'}';}public String getName() {return name;}public void setName(String name) {this.name = name;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}
}

Person.java

package com.sourceinport.demo.bean;import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;import java.util.Date;
import java.util.List;
import java.util.Map;@PropertySource(value = {"classpath:person.properties"})
@Component
@ConfigurationProperties(prefix = "person")
public class Person {private String lastName;private Integer age;private Boolean boss;private Date birth;private Map<String, Object> maps;private List<Object> lists;private Dog dog;@Overridepublic String toString() {return "Person{" +"lastName='" + lastName + '\'' +", age=" + age +", boss=" + boss +", birth=" + birth +", maps=" + maps +", lists=" + lists +", dog=" + dog +'}';}public String getLastName() {return lastName;}public void setLastName(String lastName) {this.lastName = lastName;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}public Boolean getBoss() {return boss;}public void setBoss(Boolean boss) {this.boss = boss;}public Date getBirth() {return birth;}public void setBirth(Date birth) {this.birth = birth;}public Map<String, Object> getMaps() {return maps;}public void setMaps(Map<String, Object> maps) {this.maps = maps;}public List<Object> getLists() {return lists;}public void setLists(List<Object> lists) {this.lists = lists;}public Dog getDog() {return dog;}public void setDog(Dog dog) {this.dog = dog;}
}

HelloService.java

package com.sourceinport.demo.service;public class HelloService {
}

beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><bean id = "helloService" class = "com.sourceinport.demo.service.HelloService"></bean>
</beans>

DemoApplicationTests.java

package com.sourceinport.demo;import com.sourceinport.demo.bean.Person;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.junit4.SpringRunner;@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {@AutowiredApplicationContext ioc;@Testpublic void testHelloService(){boolean b = ioc.containsBean("helloService");System.out.println(b);}
}

Spring Boot中的方法

Spring Boot中推荐使用给容器中添加组建的方式（全注解方式）

@configuration指明当前类是一个配置类，就是来替代上面的xml文件的。

@Bean：将方法的返回值添加到容器中，容器中这个组建默认的id就是方法名；

程序逻辑结构如下：

运行截图如下：

}

MyAppConfig.java

package com.sourceinport.demo.config;import com.sourceinport.demo.service.HelloService;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class MyAppConfig {@Beanpublic HelloService helloService(){System.out.println("配置@Bean给容器中添加组建");return new HelloService();}
}

HelloService.java

package com.sourceinport.demo.service;public class HelloService {
