SSM框架整合

IDEA整合SSM框架

今天自己手动搭建一下SSM框架，重温一下自己之前实习的项目。

开发环境

IEDA 2020.3
Tomcat 10.0.5
Maven 3.6.3
Mysql 8.0.23

idea新建maven项目

配置依赖，pom.xml

jdbc.properties 配置数据库相关属性

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.181.128:3306/library?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=981001

在 spring.xml 中配置 Spring 和 Mybatis 的整合

<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:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
">
    
    <context:property-placeholder location="classpath:jdbc.properties" />

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="${jdbc.username}">property>
        <property name="password" value="${jdbc.password}">property>
        <property name="jdbcUrl" value="${jdbc.url}">property>
        <property name="driverClass" value="${jdbc.driver}">property>
        <property name="initialPoolSize" value="5">property>
        <property name="maxPoolSize" value="10">property>
    bean>

    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource">property>
        <property name="mapperLocations" value="classpath:com/dasheng/repository/*.xml">property>
        <property name="configLocation" value="classpath:config.xml">property>
    bean>

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

beans>

config.xml 中配置一些 MyBatis 辅助信息，比如打印 SQL 等。

<configuration>
    <settings>
        
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    settings>

    <typeAliases>
        
        <package name="com.dasheng.entity"/>
    typeAliases>

configuration>

配置 springmvc.xml

<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-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    
    <mvc:annotation-driven>mvc:annotation-driven>
    
    <context:component-scan base-package="com.dasheng">context:component-scan>

    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/">property>
        <property name="suffix" value=".jsp">property>
    bean>
beans>

实体类Book

package com.dasheng.entity;

import lombok.Data;

@Data
public class Book {
    private int id;
    private String name;
    private String author;
    private double price;
}

BookRepository

package com.dasheng.repository;

import com.dasheng.entity.Book;

import java.util.List;

public interface BookRepository {
    public List<Book> findAll();
}

BookRepository.xml

<mapper namespace="com.dasheng.repository.BookRepository">
    <select id="findAll" resultType="Book">
        select * from book
    select>
mapper>

BookService

package com.dasheng.service;

import com.dasheng.entity.Book;

import java.util.List;

public interface BookService {
    public List<Book> findAll();
}

BookServiceimpl

package com.dasheng.service.impl;

import com.dasheng.entity.Book;
import com.dasheng.repository.BookRepository;
import com.dasheng.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookServiceImpl implements BookService {

    @Autowired
    private BookRepository bookRepository;

    @Override
    public List<Book> findAll() {
        return bookRepository.findAll();
    }
}

BookHandler

package com.dasheng.controller;

import com.dasheng.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/book")
public class BookHandler {
    @Autowired
    private BookService bookService;

    @GetMapping("/findAll")
    public ModelAndView findAll(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("index");
        modelAndView.addObject("list", bookService.findAll());
        return modelAndView;
    }
}

此时SSM框架就整合完成了，我的目录结构如下：
