SSM（Spring MVC +Spring+Mybatis）整合——maven工程

我不是女神ヾ 2021-12-23 11:55 214阅读 0赞

所谓的SSM 其实就是Spring MVC下整合mybatis。

具体的定义网络上都有，很详细。

这里只说项目的搭建步骤。

第一步

新建maven工程

工程目录如下：

配置pom.xml文件，引入所需的jar包

第二步 Spring MVC和mybatis的整合

springmvc.xml文件

mybatis的全局配置文件

sqlMapConfig.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">

            <package name="com.book.model"/>
        </typeAliases>
    
        
    
        
    </configuration>

mysql数据库的配置文件

db.properties文件

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/booktest
    jdbc.username=root
    jdbc.password=root

附：配置文件目录：

第三步、开始写代码

Java 目录：

![1077876-20170111164749103-57240371.png][]

model层：

Person.java

public class Person {
    
        private Integer id;
        private String  name;
        private Integer age;
        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;
        }
        public Integer getAge() {
            return age;
        }
        public void setAge(Integer age) {
            this.age = age;
        }
        
        public Person(){
            super();
        }
        
         @Override
            public String toString() {
                return "Person [Id=" + id + ", Name=" + name
                        + ", age=" + age + "]";
            }
    
    }

service层:

PersonService.java

public interface PersonService {
    
         public Person find(int id);
         public List<Person> FindAll();
    }

PersonServiceImpl.java

@Service
    public class PersonServiceImpl implements PersonService{
    
          @Autowired
            private PersonMapper personDao;
            public void setUserDao(PersonMapper personDao) {
                this.personDao = personDao;
            }
    
            public Person find(int id) {
                // TODO Auto-generated method stub
                return personDao.find(id);
            }
    
            public List<Person> FindAll() {
                // TODO Auto-generated method stub
                return personDao.FindAll();
            }
    }

dao层

PersonMapper.java

public interface PersonMapper {
         public Person find(int id);
         public List<Person> FindAll();
    }

PersonMapper.xml

PersonController.java

@Controller
    public class PersonController {
        @Autowired
        private PersonService personService;
    
        public void setUserService(PersonService personService) {
            this.personService = personService;
        }
    
        @RequestMapping("/person")
        public ModelAndView person(){
            Person person =personService.find(1);
            String str= person.toString();
            return new ModelAndView("message","str",str);
        }
        @RequestMapping("/personlist")
        public ModelAndView personlist(){
            List<Person> person= new ArrayList<Person>();
                person=personService.FindAll();
            JSONObject json=new JSONObject();
            json.put("person", person);
            return new ModelAndView("message","str",json);
        }
