SSM框架搭建

2020-09-19 19:01:07  阅读：218  来源： 互联网

标签：框架 spring commons springframework SSM version org log4j 搭建


１.进行项目需求分析，建立数据库模型并建立数据表，在此不做详细描述；

２.创建基于Maven的Web项目，项目基本结构如下：

３.ｐｏｍ．ｘｍｌ所需的依赖如下：

４.日志输出文件配置

### set log levels ###
log4j.rootLogger = DEBUG,Console,File

###  输出到控制台  ###
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%d{yy/MM/dd HH:mm:ss:SSS}]-[%t]-%p --- [%100.100l] --- %m%n

### 输出到日志文件 ###
log4j.appender.File=org.apache.log4j.RollingFileAppender
log4j.appender.File.File=${project}src\\main\\resources\\out\\app.log
log4j.appender.File.MaxFileSize=10MB
log4j.appender.File.Threshold=ALL
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=[%d{yy/MM/dd HH:mm:ss:SSS}] - [%t] - %p --- [%100.100l] --- %m%n

５.建立数据库连接的基本配置文件，建议使用外部配置，便于修改（此处所给的是阿里巴巴的德鲁伊数据源相关的ｊｄｂｃ配置）：

driverClassName=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/hrm_db?useSSL=false&serverTimezone=GMT&allowPublicKeyRetrieval=true
#用户名不可键不可为username 否则 会报错 Access denied for user 'KeLuo'@'localhost' (using password: YES)
name=sahara
password=12345
initialSize=100
maxActive=100
maxWait=3000
minIdle=5
ｄｒｕｉｄ．properties

 

 

６.Ｍｙｂａｔｉｓ框架的基本配置（因与Spring集成，其内的环境配置均舍弃不写，相关配置如数据源等在Spring的基本配置文件中配置）

<?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">
<!-- mybats的主配置文件 -->
<configuration>
    <!--配置延迟加载策略-->
    <settings>
        <!-- 全局映射器启用或禁用缓存
        <setting name="cacheEnable" value="true"/> -->
        <!-- 允许JDBC支持生成的键，需要适当的驱动。 -->
        <setting name="useGeneratedKeys" value="true"/>
        <!-- 配置默认的执行器 -->
        <setting name="defaultExecutorType" value="REUSE"/>
        <!--打开延迟加载开关-->
        <setting name="lazyLoadingEnabled" value="true"/>
        <!--将积极加载改为消息加载，即按需加载-->
        <setting name="aggressiveLazyLoading" value="false"/>
        <!-- 设置超时时间，决定驱动等待一个数据库响应的时间 -->
        <setting name="defaultStatementTimeout" value="25000"/>
    </settings>
    <!--配置别名-->
    <typeAliases>
        <!--<typeAlias type="com.sahara.entity.Role" alias="Role" />-->
        <package name="com.sahara.domain"/>
    </typeAliases>
    <!--指定映射配置文件（每个Dao独立的配置文件）的位置-->
    <mappers>
        <!--<mapper resource="com/sahara/mappers/IRoleDao.xml"></mapper>-->
        <package name="com.sahara.dao"/>
    </mappers>
</configuration>

７.Spring的基本配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- 扫描base-package包下的java文件，有Spring相关注解的类，则把这些类注册为Spring的bean -->
    <context:component-scan base-package="com.sahara"/>

    <!-- 使用PropertyOverrideConfigurer后处理器加载数据源参数 -->
    <context:property-placeholder location="classpath:druid.properties"/>

    <!-- 配置druid数据源 -->

    <!-- 配置SqlSessionFactory，org.mybatis.spring.SqlSessionFactory是Mybatis社区开发用于整合Spring的bean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
          p:dataSource-ref="dataSource"
          p:configLocation="classpath:mybatisConfig.xml"/>

８.Spring　MVC的基本配置文件

<?xml version="1.0" encoding="utf-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">



    <!-- 自动扫描base-package包下用了@Controller注解的类并将其注册为Spring的Controller -->
    <context:component-scan base-package="com.sahara.controller"/>

    <!-- 设置默认配置方案 -->
    <mvc:annotation-driven/>

    <!-- 视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 前缀 -->

１０.根据数据库建立相应的实体类（可使用Lombok插件以生成Getter与Setter方法）

 

１１.使用Ｍｙｂａｔｉｓ技术建立数据访问层（包括接口及XML文件）

１２.创建测试类对数据访问层进行测试，测试类应引入相关配置，（若无＠Run With　与　ContextConfiguration注解，则其内部使用注解会报Null PointException）

package com.sahara.dao;

import com.sahara.dao.UserDao;
import com.sahara.domain.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.transaction.annotation.Transactional;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:applicationContext.xml"})
@Transactional
public class UserTest {

    @Autowired
    public UserDao userDao;

    @Test
    public void testselectById() {
        User user = userDao.selectById(1);
        System.err.println(user);
    }
}
