入门级最强SSM整合(简便易懂注解和配置文件)idea

时间:2020-9-16 作者:admin

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

        <url-pattern>/</url-pattern>
    </filter-mapping>
</web-app>

 

  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<User> getUsers();
}

UserService.interface

package com.hu.service;

import com.hu.pojo.User;

import java.util.List;

public interface UserService {
    List<User> 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<User> 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<User> users = userService.getUsers();
        model.addAttribute("users", users);
        return "list";
    }


}

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

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
    <!--    不去扫描controller包-->
    <context:component-scan base-package="com.hu">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
        <property name="password" value="root"/>
        <property name="user" value="root"/>

        <!--        #改成自己的并补充完整  mysql8略有不同-->

        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/>
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    </bean>

    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hu.mapper"/>
    </bean>

</beans>

springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--    扫描controller包-->
    <context:component-scan base-package="com.hu.controller"/>
    <!--    开启注解-->
    <mvc:annotation-driven/>
    <!--    资源过滤-->
    <mvc:default-servlet-handler/>

    <!--  视图解析器  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <!--        前缀-->
        <property name="prefix" value="/WEB-INF/pages/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>


</beans>

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
