Spring + SpringMVC + Mybatis 整合(.xml)

• 整合需要的依赖(Maven项目下的pom.xml)：

• web.xml(WEB-INF下)

    
        contextConfigLocation
        classpath:applicationContext.xml
    

    
    
        enc
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            utf-8
        
        
            forceEncoding
            true
        
    
    
        enc
        /*
    

    
    
        dispatcher
        org.springframework.web.servlet.DispatcherServlet
    

    
        dispatcher
        /
    

    
    
        
            org.springframework.web.context.ContextLoaderListener
        
         

• 与之对应的(前端控制器名-servlet.xml)，同在WEB-INF下

• applicationContext.xml(如果是Maven项目，一般放在src/main/resources目录下)

• 新建一个mapper的package来管理mapper(有mapper接口及对应的xml文件)
  在此包下我写了一个BookMapper的接口(同时对应一个BookMapper.xml文件)

package com.qfedu.ssm.mapper;
import java.util.List;
import com.qfedu.ssm.entity.Book;

public interface BookMapper {   
    public List findByTypeId(int typeId);
}

    
    
    
        select * from tb_book where typeid=#{typeId}
