Question

我开发了一个Spring应用程序，它覆盖Setter Injection超过Constructor Injection，但是getter函数会产生错误。

public class Book {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Book(String name) {
        this.name = name;
    }

}

Spring.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-3.0.xsd">

    <bean id="bookBean" class="com.abc.xyz.Book">
        <property name="name" value="ABCD"></property>
        <constructor-arg value="EFGH"></constructor-arg>
    </bean>
</beans>

ClientApp.java：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ClientApp {
    ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
    Book book = (Book) context.getBean("bookBean");
    book.getName();
}

请求Bean函数生成错误
