springmvc mybatis整合

 

 

首先是pom.xml，下面列出的dependency有些是多余的，因为项目其他的功能需要才加的，可以根据情况增删。

controller:

 

package com.tch.test.springmvcmybatis.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.tch.test.springmvcmybatis.service.BlogService;

//@Scope("prototype")				//这样可以让控制器是原型模式，而不是单例(spring mvc建议controller使用单例) 
@Controller("helloWorld")
// 表示这个类是后端控制器
@RequestMapping("/namespace")
// 在类上面加上@RequestMapping，则该类下面的方法的访问路径都需要加上该前缀，类似struts2的namespace
public class HelloWorldController {

	@Autowired
	private BlogService blogService;

	@RequestMapping("/getBlog")
	public String getBlog(Model model) {
		model.addAttribute("message",
				blogService.getBlog("ACTIVE", "dreamoftch-1", "title-1"));
		return "helloWorld";
	}

}

 

 

package com.tch.test.springmvcmybatis.service;

import java.util.List;

import org.apache.ibatis.annotations.Param;

import com.tch.test.springmvcmybatis.bean.Blog;

public interface BlogService {

	List<Blog> getBlog(@Param("status") String status, @Param("author") String author, @Param("title") String title);
	
}

 

package com.tch.test.springmvcmybatis.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.tch.test.springmvcmybatis.bean.Blog;
import com.tch.test.springmvcmybatis.mapper.BlogMapper;

@Service
@Transactional
public class BlogServiceImpl implements BlogService{

	@Autowired
	private BlogMapper blogMapper;
	
	public List<Blog> getBlog(String status, String author, String title) {
		return blogMapper.getBlog();
	}

	
}

 

 

package com.tch.test.springmvcmybatis.mapper;

import java.util.List;

import com.tch.test.springmvcmybatis.bean.Blog;

public interface BlogMapper {
	
//	List<Blog> getBlog(@Param("status") String status, @Param("author") String author, @Param("title") String title);
	
	List<Blog> getBlog();
	
}

 

跑起来之后，通过URL：

 

 localhost:8080/springmvc-mybatis/mvc/namespace/getBlog

 

即可访问。

 

OK。
