Spring系列【07】零配置实现Bean的注入

与前几例不同，需要导入aop包。

Book.java 注意Book类@Component

package cn.com.xf;

import org.springframework.stereotype.Component;

@Component
public class Book {
private String name="JAVA从入门到精通";
private double price=45.67;
public String getName() {
return name;
}
@Override
public String toString() {
return "Book [name=" + name + ", price=" + price + "]";
}
public void setName(String name) {
this.name = name;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
}

Person.java Person类@Component

package cn.com.xf;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class Person {
private String address="河南省南阳市";
@Autowired
private Book book;
public String getAddress() {
return address;
}
@Override
public String toString() {
return "Person [address=" + address + ", book=" + book + "]";
}
public void setAddress(String address) {
this.address = address;
}
public Book getBook() {
return book;
}
public void setBook(Book book) {
this.book = book;
}
}

Spring配置文件：注意<context:annotation-config/>
