泛型依賴注入

1.定義泛型

Java代碼：

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.實(shí)現(xiàn)基類，聲明泛型

Java代碼：

package com.spring.generic;

import org.springframework.stereotype.Service;

@Service
public class GUserService extends BaseService<GUser> {

}

xml代碼：
