入门级最强SSM整合(简便易懂注解和配置文件)idea

目录

环境

1.  新建一个Maven项目 （选择webapp注意不要选cocoon的）

 2.  输入Name Group​

 3.  Add Maven Property（可省略）

4.  建各种包

java和resource包都要直接双击就行了 

在main包下新建test包并标记

最后附上项目里所有的包结构 以及pom.xml

web.xml

 

  5.  编写各种类

User.class

UserMapper.interface

UserService.interface

UserServiceImpl.class

UserController.class

6.  编写resources中的applicationContext.xml和springmvc.xml

applicationContext.xml

springmvc.xml

7.  启动tomcat进行测试是否整合完成

启动前建议把项目结构中modules中的spring放在同一个applicationContext中

        characterEncodingFilter
        /
    

 

  5.  编写各种类

User.class

package com.hu.pojo;

public class User {

    private Integer id;
    private String name;

    public User() {
    }

    public User(Integer id, String name) {
        this.id = id;
        this.name = name;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

UserMapper.interface

package com.hu.mapper;

import com.hu.pojo.User;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface UserMapper {

也可选择用xml文件进行CRUD

    @Select("select * from user")
    List getUsers();
}

UserService.interface

package com.hu.service;

import com.hu.pojo.User;

import java.util.List;

public interface UserService {
    List getUsers();
}

UserServiceImpl.class

package com.hu.service.impl;

import com.hu.mapper.UserMapper;
import com.hu.pojo.User;
import com.hu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper mapper;

    @Override
    public List getUsers() {
        return mapper.getUsers();
    }
}

UserController.class

package com.hu.controller;

import com.hu.pojo.User;
import com.hu.service.UserService;
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 java.util.List;

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/list")
    public String list(Model model) {
        List users = userService.getUsers();
        model.addAttribute("users", users);
        return "list";
    }


}

6.  编写resources中的applicationContext.xml和springmvc.xml

applicationContext.xml

springmvc.xml

7.  启动tomcat进行测试是否整合完成

启动前建议把项目结构中modules中的spring放在同一个applicationContext中
