泛型依赖注入
1.定义泛型
Java代码:
package com.spring.generic;
import org.springframework.beans.factory.annotation.Autowired;
public class BaseService<T> {
@Autowired
protected BaseRepository<T> repository;
public void add() {
System.out.println("BaseService Add user");
System.out.println(repository);
}
}
2.实现基类,声明泛型
Java代码:
package com.spring.generic;
import org.springframework.stereotype.Service;
@Service
public class GUserService extends BaseService<GUser> {
}
xml代码:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<context:component-scan base-package="com.spring.generic">
</context:component-scan>
</beans>
