我的第一个ssm项目

第一步（建一个数据库表）

数据库文件

/*
Navicat MySQL Data Transfer

Source Server         : MySQL
Source Server Version : 80019
Source Host           : localhost:3306
Source Database       : ssmbuild

Target Server Type    : MYSQL
Target Server Version : 80019
File Encoding         : 65001

Date: 2020-05-18 00:17:41
*/

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `books`
-- ----------------------------
DROP TABLE IF EXISTS `books`;
CREATE TABLE `books` (
  `bookID` int NOT NULL AUTO_INCREMENT COMMENT '娑旑洀d',
  `bookName` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '书名',
  `bookCounts` int NOT NULL COMMENT '涔︾殑鏁伴噺',
  `detail` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '书的表述',
  PRIMARY KEY (`bookID`),
  KEY `bookID` (`bookID`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of books
-- ----------------------------
INSERT INTO `books` VALUES ('1', 'Java', '111', '从入门到放弃');
INSERT INTO `books` VALUES ('2', 'MySQL222', '10', '从删库到跑路');
INSERT INTO `books` VALUES ('3', 'Linux', '5', '从进门到进牢');
INSERT INTO `books` VALUES ('4', 'xsa', '21', 'xs');
INSERT INTO `books` VALUES ('9', 'aaa', '2', '2');

第二步（建一个Maven项目）

第三步（ 建立基本结构和配置框架 ）

• com.wxs.pojo

• com.wxs.dao

• com.wxs.service

• com.wxs.controller

• mybatis-config.xml

  
  
  <configuration>
      
  configuration>
  

• applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"  
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd"> 
    
beans>

第四步（编写持久层）

• com.wxs.pojo.Books.java

  package com.wxs.pojo;
  
  import lombok.AllArgsConstructor;
  import lombok.Data;
  import lombok.NoArgsConstructor;
  
  @Data
  @AllArgsConstructor
  @NoArgsConstructor
  public class Books {
      private int bookID;
      private String bookName;
      private int bookCounts;
      private String detail;
  }
  
  

• com.wxs.dao.BookMap.java

  package com.wxs.dao;
  
  import com.wxs.pojo.Books;
  import org.apache.ibatis.annotations.Param;
  
  import java.util.List;
  
  public interface BookMap {
      public int addBook(Books books);
      public int deleteBook(@Param("bookID") int id);
      public int updateBook(Books books);
      public Books findById(@Param("bookID") int id);
      public List<Books> findBooks();
      public List<Books> findByName(@Param("bookName") String name);
  }
  
  

• com.wxs.dao.BookMap.xml

<mapper namespace="com.wxs.dao.BookMap">
    <insert id="addBook" parameterType="books">
        insert into ssmbuild.books(bookID, bookName, bookCounts, detail)
        values (null, #{bookName}, #{bookCounts}, #{detail});
    insert>
    <delete id="deleteBook">
        delete ssmbuild.books
        from ssmbuild.books
        where bookID = #{bookID}
    delete>
    <update id="updateBook" parameterType="books">
        update ssmbuild.books
        set bookCounts =#{bookCounts},bookName = #{bookName},detail = #{detail}
        where bookID = #{bookID} ;
    update>
    <select id="findById" resultType="books">
        select *
        from ssmbuild.books where bookID = #{bookID};
    select>
    <select id="findBooks" resultType="books">
        select *
        from ssmbuild.books;
    select>
    <select id="findByName" resultType="books" parameterType="String">
        select *
        from ssmbuild.books where bookName like '%${bookName}%';
    select>
mapper>database.properties

• database.properties( 编写MyBatis的核心配置文件 )

  
  
  
     
        
    
  //配置别名
      
          
      
  
      
  
  
  

• 数据库配置文件 （database.properties）

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuilduseUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
jdbc.username=root
jdbc.password=root

第五步（编写业务层）

• com.wxs.service.BookService(接口)

  package com.wxs.service;
  
  import com.wxs.pojo.Books;
  import org.apache.ibatis.annotations.Param;
  
  import java.util.List;
  
  public interface BookService {
      public int addBook(Books books);
      public int deleteBook(int id);
      public int updateBook(Books books);
      public Books findById(int id);
      public List<Books> findBooks();
      public List<Books> findBookName(String name);
  }
  
  

• com.wxs.service.BookService(实现类)

  package com.wxs.service;
  
  import com.wxs.dao.BookMap;
  import com.wxs.pojo.Books;
  
  import java.util.List;
  
  public class BookServiceImpl implements BookService {
      BookMap bookMap;
  
      public void setBookMap(BookMap bookMap) {
          this.bookMap = bookMap;
      }
  
      public int addBook(Books books) {
          return bookMap.addBook(books);
      }
  
      public int deleteBook(int id) {
          return bookMap.deleteBook(id);
      }
  
      public int updateBook(Books books) {
          return bookMap.updateBook(books);
      }
  
      public Books findById(int id) {
          return bookMap.findById(id);
      }
  
      public List<Books> findBooks() {
          return bookMap.findBooks();
      }
  
      public List<Books> findBookName(String name) {
          return bookMap.findByName(name);
      }
  }
  
  

  第六步（spring整合dao和service）

• spring-dao.xml

         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
         https://www.springframework.org/schema/context/spring-context.xsd">
     
     
      <context:property-placeholder location="classpath:database.properties"/>
     
     
      <bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
           
          <property name="jdbcUrl" value="${jdbc.url}"/>
          <property name="user" value="${jdbc.username}"/>
          <property name="password" value="${jdbc.password}"/>
          <property name="driverClass" value="${jdbc.driver}"/>
          
          <property name="maxPoolSize" value="30"/>
          <property name="minPoolSize" value="10"/>
           
          <property name="autoCommitOnClose" value="false"/>
           
          <property name="checkoutTimeout" value="10000"/>
          
          <property name="acquireRetryAttempts" value="2"/>
      bean>
    
      <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">
           
          <property name="dataSource" ref="dataSource"/>
            
          <property name="configLocation" value="classpath:mybatis-config.xml"/>
      bean>
         
     
      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
          <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
           
          <property name="basePackage" value="com.wxs.dao"/>
      bean>
  beans>
  

• spring-service.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"
         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">
         
      <context:component-scan base-package="com.wxs.service"/>
         
      <bean class="com.wxs.service.BookServiceImpl" id="service">
          <property name="bookMap" ref="bookMap"/>
      bean>
         
      <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">
          <property name="dataSource" ref="dataSource"/>
      bean>
  
  beans>
  

  第七步（编写controller层，并整合）

  spring-mvc.xml

  
  <beans xmlns="http://www.springframework.org/schema/beans"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

      <mvc:annotation-driven/>
  
      <mvc:default-servlet-handler/>
  
      <context:component-scan base-package="com.wxs.controller"/>
  
      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/jsp/"/>
          <property name="suffix" value=".jsp"/>
      bean>
  
  beans>
  

  web.xml

  
  <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
