springmvc基础搭建步骤

一：创建maven项目

这个不用多说，在myeclipse中直接创建web项目加上maven即可

* 二：在maven中引入jar包*
在项目中找到pom.xml文件，然后将自己想要导入的jar包在maven库里找到然后复制粘贴进来
下面我将一些常用的jar包的导入复制过来

    <dependency>
        <groupId>org.springframeworkgroupId>

三：配置web.xml文件
下面是我对web.xml文件的一些配置，具体都有说明

<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
  <display-name>display-name> 
  <welcome-file-list>
    <welcome-file>index.jspwelcome-file>
  welcome-file-list>

  
  <context-param>
    <param-name>contextConfigLocationparam-name>
    <param-value>classpath:applicationContext.xmlparam-value>
  context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>

  <servlet>
    <servlet-name>mvcservlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
    <init-param>
      <param-name>contextConfigLocationparam-name>

      <param-value>trueparam-value>
    init-param>
  filter>
  
  <filter-mapping>
    <filter-name>encodingFilterfilter-name>
    <url-pattern>/*url-pattern>

  filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilterfilter-name>
    <url-pattern>/*url-pattern>
  filter-mapping>
web-app>

四：application.xml配置

<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"

    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">

    

    
    
    
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">            
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm_crud?useUnicode=true&characterEncoding=UTF-8" />
        <property name="user" value="root" />
        <property name="password" value="root" />       
    bean>
    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        
        <property name="configLocation" value="classpath:myBatis-config.xml" />
        
        <property name="mapperLocations" value="classpath:hpu/mapper/*.xml"/>

    bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactory" ref="sqlSessionFactory"/>
        
        <property name="basePackage" value="hpu"/>
    bean>


    

    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource" />
    bean>
    
    <tx:advice id="advice" transaction-manager="transactionManager">
        <tx:attributes>
    
            <tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="*" propagation="SUPPORTS"/>
            <tx:method name="get*" read-only="true"/>
        tx:attributes>
    tx:advice>
    
    

    
    
    <aop:config>
        <aop:advisor advice-ref="advice" pointcut="execution(* hpu.service..*(..))"/>
    aop:config>

     
    <context:component-scan base-package="hpu">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    context:component-scan>   

        





    
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"/>     
        <constructor-arg name="executorType" value="BATCH">constructor-arg>
    bean>

    


beans>

五：配置springmvc.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"
    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-3.2.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
    ">

    
    
    
    <context:component-scan base-package="hpu" use-default-filters="false">
        
        <context:include-filter type="annotation"
            expression="org.springframework.stereotype.Controller" />
        
    context:component-scan>
    
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/">property>
        <property name="suffix" value=".jsp">property>
    bean>

    
    
    <bean class="org.springframework.web.servlet.view.BeanNameViewResolver">
        <property name="order" value="100">property>
    bean>


    
    
    <mvc:default-servlet-handler/>
    
    <mvc:annotation-driven>mvc:annotation-driven>



beans>

六：mybatis逆向生成方法
配置mybatis全局配置文件，可以直接去mybatis官方搜索

 

<configuration>
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    settings>
    
    <typeAliases>
            <package name="hpu.bean"/>
    typeAliases>
    <plugins>
        
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            
            <property name="reasonable" value="true"/>
        plugin>
    plugins>
configuration>

去百度搜索mybatis generator可查看具体操作
先添加jar文件，然后在项目之下创建mbg.xml文件

<generatorConfiguration>

  <context id="DB2Tables" targetRuntime="MyBatis3">
     <commentGenerator>
      <property name="suppressAllComments" value="true" />
    commentGenerator>
    <jdbcConnection driverClass="com.mysql.jdbc.Driver"
        connectionURL="jdbc:mysql://localhost:3306/ssm_crud"
        userId="root"
        password="root">
    jdbcConnection>

    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    javaTypeResolver>
    
    <javaModelGenerator 
        targetPackage="hpu.bean" 
        targetProject=".\src\main\java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    javaModelGenerator>

    
    <sqlMapGenerator 
        targetPackage="hpu.mapper"  
        targetProject=".\src\main\java">
      <property name="enableSubPackages" value="true" />
    sqlMapGenerator>

    
    <javaClientGenerator type="XMLMAPPER" 
        targetPackage="hpu.dao" 
        targetProject=".\src\main\java">
      <property name="enableSubPackages" value="true" />
    javaClientGenerator>

    
    <table tableName="tbl_emp" domainObjectName="Employee">
    table>
    <table tableName="tbl_dept" domainObjectName="Department">
    table>

  context>
generatorConfiguration>

再创建一个java文件，直接运行即可创建

package hpu.test;

import java.io.File;
import java.util.ArrayList;
import java.util.List;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;

public class MBGTest {
    public static void main(String[] args) throws Exception {

        List warnings = new ArrayList();
        boolean overwrite = true;
        File configFile = new File("mbg.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
                callback, warnings);
        myBatisGenerator.generate(null);
    }
}
