我是靠谱客的博主 淡淡大树,最近开发中收集的这篇文章主要介绍IDEA 创建 maven聚合项目-ssm框架,觉得挺不错的,现在分享给大家,希望可以做个参考。

概述

IDEA 创建 maven聚合项目-ssm框架:

  1. 创建一个空文件夹 在本地 然后用idea打开此空文件夹
    在这里插入图片描述

  2. 选中huoni ,添加huoni-parent 父模块
    在这里插入图片描述
    在这里插入图片描述

  3. 选中huoni 创建 huoni-common模块 ,指定父模块为huoni-parent
    在这里插入图片描述

  4. huoni-biz模块同3

  5. 创建huoni-web模块 ,创建同3, 需要添加web.xml . 打开 model settings
    在这里插入图片描述
    第一步:需要修改web.xml位置为 srcmainwebappWEB-INFweb.xml.
    第二步: 需修改webapp的位置为 srcmainwebapp

  6. 指定 web 模块为 war包 ,parent 的为pom ,其他为jar包。并添加必要依赖。如 parent的pom文件

</project>
  1. 将各模块所需的jar包添加到各自的pom文件中
  2. 配置 web.xml文件
    加载spring 文件、配置spring监听器、配置mvc前端控制器、配置乱码过滤器等。
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <!--指定spring初始化文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:/spring/*-beans.xml</param-value>
    </context-param>
     <!--spring监听器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!--mvc 前端控制器-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:/web/web-main.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--乱码过滤器-->
    <filter>
        <filter-name>encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>
  1. 配置 mvc配置文件在 前端控制器指定的位置。
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/mvc
    					http://www.springframework.org/schema/mvc/spring-mvc.xsd
    					http://www.springframework.org/schema/context
    					http://www.springframework.org/schema/context/spring-context.xsd">

    <!--扫描controller-->
    <context:component-scan base-package="com.huonilaifu.web"/>

     <!--映射器和适配器-->
    <mvc:annotation-driven/>

    <!--视图解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

10 .先验证 mvc的配置,在 mvc配置文件扫描包的下边创建一个controller,启动验证。

package com.huonilaifu.web.upload;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @author: lirb
 * @date: 2019/4/1
 * @description:
 */
@Controller
@RequestMapping("/upload")
public class UploadController {

    @ResponseBody
    @RequestMapping(value = "/upload",method = RequestMethod.GET,produces = {"application/json;charset=utf-8"})
    public String upload(){
        return "upload";
    }

}

在这里插入图片描述
11. 配置 mybatis
添加响应的 mapper接口、model、mapper文件
配置文件如下

<?xml version="1.0" encoding="UTF-8"?>
<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-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/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
	http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">

    <aop:aspectj-autoproxy proxy-target-class="true"/>

    <!--扫描service-->
    <context:component-scan base-package="com.huonilaifu">
        <context:exclude-filter type="annotation"
                                expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!--加载属性配置文件-->
    <context:property-placeholder ignore-unresolvable="true" location="classpath:application.properties"/>

    <!--配置数据源datasource-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${server.driver}" />
        <property name="url" value="${server.url}"></property>
        <property name="username" value="${server.username}"></property>
        <property name="password" value="${server.password}"></property>
        <!-- 初始化连接大小 -->
        <property name="initialSize" value="${server.initialSize}"></property>
        <!-- 连接池最大数量 -->
        <property name="maxActive" value="${server.maxActive}"></property>
        <!-- 连接池最大空闲 -->
        <property name="maxIdle" value="${server.maxIdle}"></property>
        <!-- 连接池最小空闲 -->
        <property name="minIdle" value="${server.minIdle}"></property>
        <!-- 获取连接最大等待时间 -->
        <property name="maxWait" value="${server.maxWait}"></property>

    </bean>
    <!--配置sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
    </bean>
    <!--配置mapper接口扫描器mapperScannerConfigurer01-->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
        <property name="basePackage" value="com.huonilaifu.upload.dao"></property>
    </bean>
    <!--配置SqlSessionTemplate-->
    <bean id="sqlSession" name="sqlSession" class="org.mybatis.spring.SqlSessionTemplate" scope="prototype">
    <constructor-arg index="0" ref="sqlSessionFactory"/>
    </bean>
    <!--配置事务管理器-->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--配置切面-->
    <tx:advice id="txAdvice" transaction-manager="txManager" >
        <tx:attributes>
            <tx:method name="select*" read-only="true"/>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>
    <!--配置切入点-->
    <aop:config>
        <aop:pointcut id="appService"  expression="execution(* com.huonilaifu.upload.service..*Service*.*(..))"  ></aop:pointcut>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="appService"></aop:advisor>
    </aop:config>
</beans>

相关service

package com.huonilaifu.upload.service.impl;

import com.huonilaifu.upload.dao.UserInfoMapper;
import com.huonilaifu.upload.model.UserInfo;
import com.huonilaifu.upload.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * @author: lirb
 * @date: 2019/4/1
 * @description:

@Service
public class UserServiceImpl implements UserService {

@Autowired
private UserInfoMapper userInfoMapper;



    public List<UserInfo> selectAll() {
        List<UserInfo> userInfos = userInfoMapper.selectAll();
        return userInfos;
    }

}

相关mapper接口

package com.huonilaifu.upload.dao;

import com.huonilaifu.upload.model.UserInfo;

import java.util.List;


public interface UserInfoMapper {
  
    List<UserInfo> selectAll();

}

请求访问 如有报http status 406 – not acceptable
说明使用注解@ResponseBody 返回实体 没有序列化的jar报需添加
