• SSM整合

    1、创建项目，然后配置maven

     

    配置好maven 

     引入文件夹

     

     

     2、引入依赖

    1. <properties>
    2.     <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
    3.     <maven.compiler.source>1.8maven.compiler.source>

    3、配置tomcat 

     

     

    准备好这些包、方便等下测试

    com.xg.controller

    com.xg.service

    com.xg.dao

    com.xg.pojo

     

    4、配置springmvc和spring

     

    配置web.xml 

    1. <web-app>
    2.   <display-name>Archetype Created Web Applicationdisplay-name>
    3.   
    4.   <context-param>

    51.     <url-pattern>/*url-pattern>
    52.   filter-mapping>
    53. web-app>

     

    创建dispatcher-servlet.xml

    配置 dispatcher-servlet.xml

    1. "1.0" encoding="UTF-8"?>
    2. <beans xmlns="http://www.springframework.org/schema/beans"
    3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    4.        xmlns:context="http://www.springframework.org/schema/context"
    5.        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

    37.     mvc:annotation-driven>
    38.  
    39. beans>
    40.

     创建

    applicationContext.xml

     创建包views

    在包下创建success.html

    5、测试

    创建TestController 

    1. @Controller
    2. public class TestController {
    3.     @RequestMapping(value = "/hi")
    4.     public String hi() {
    5.         System.out.println("TestController hi()");
    6.         return "success";
    7.     }
    8. }

    整合mybatis 

    创建jdbc.properties

    1. jdbc.userName=root
    2. jdbc.password=123456
    3. jdbc.driverClass=com.mysql.jdbc.Driver
    4. jdbc.url=jdbc:mysql://localhost:3306/ssm?userSSL=true&userUnicode=true&characterEncoding=UTF-8

    在pom.xml中加入

    1. <dependency>
    2.       <groupId>maven_repository.org.mybatisgroupId>
    3.       <artifactId>mybatis-springartifactId>
    4.       <version>2.0.3version>
    5.     dependency>

    applicationContext.xml编辑

    57.         tx:attributes>
    58.     tx:advice>
    59. beans>

    创建mybatis-config.xml 

    mybatis-config.xml配置

    1. "1.0" encoding="UTF-8" ?>
    2. configuration
    3.         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    4.         "http://mybatis.org/dtd/mybatis-3-config.dtd">
    5. <configuration>
    6. configuration>

    创建好数据库 

    1. CREATE DATABASE ssm;
    2. USE ssm;
    3.  
    4. CREATE TABLE person(
    5. 	id INT,
    6. 	NAME VARCHAR(32),
    7. 	age INT
    8. )
    9. INSERT INTO person VALUES(1,'张三',18);
    10. INSERT INTO person VALUES(2,'李四',20);
    11. SELECT * FROM person;

     准备好

    、

    Person

    1. public class Person {
    2.     private Integer id;
    3.     private String name;
    4.     private Integer age;
    5.  
    6.     @Override
    7.     public String toString() {
    8.         return "Person{" +
    9.                 "id=" + id +
    10.                 ", name='" + name + '\'' +
    11.                 ", age=" + age +
    12.                 '}';
    13.     }
    14.  
    15.     public Integer getId() {
    16.         return id;
    17.     }
    18.  
    19.     public void setId(Integer id) {
    20.         this.id = id;
    21.     }
    22.  
    23.     public String getName() {
    24.         return name;
    25.     }
    26.  
    27.     public void setName(String name) {
    28.         this.name = name;
    29.     }
    30.

    33.     }
    34.  
    35.     public void setAge(Integer age) {
    36.         this.age = age;
    37.     }
    38. }

    PersonDao

    3.     @Autowired
    4.     private PersonDao personDao;
    5.  
    6.     public List getPersonList(){
    7.         return personDao.getPersonList();
    8.     };
    9.  
    10. }

    TestController
