SSM整合记录

就想自己折腾，把框架聚合起来，然后发现公司的框架配置，其实官网基本都写详细了。

结合官网文档，很快可以搭出来的。不懂再看下公司项目配置，美滋滋....

1.先来全家福：

2. pom.xml配置：

3. web.xml配置：

<?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_3_1.xsd"
         version="3.1">

  <!-- 注意 /XX/*  /*  *.XX 的区别（* 和/*.do 报错了，为什么呢）-->

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

4. spring-application.xml 这里只用来了扫描service和dao 注解：

<?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/spring-context.xsd">

    <!-- Bean 扫描，过滤Controller(这个在spring-mvc.xml里扫描) -->

5. spring-mvc.xml:

6. jdbc.properties:

db.driver=com.mysql.jdbc.Driver
db.host=localhost
db.databaseName=myssm
db.url=jdbc:mysql://${db.host}:3306/${db.databaseName}?useUnicode=true&amp;characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
db.username=root
db.password=123456

db.maximum.connection.count=100
db.minimum.connection.count=1
db.simultaneous.build.throttle=3

7.mybatis-config.xml,这些个属性含义，mybatis官网很详细:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration

</beans>

9.实体类SysUser.java:

package com.renzku.POJO;

/**
 * Created by renzku on 2017/9/9.
 */
public class SysUser {
    private Long userId;
    private String userName;
    private String userText;

    public SysUser() {
    }

    public SysUser(Long userId, String userName, String userText) {
        this.userId = userId;
        this.userName = userName;
        this.userText = userText;
    }

    public Long getUserId() {
        return userId;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserText() {
        return userText;
    }

    public void setUserText(String userText) {
        this.userText = userText;
    }
}

10.userMapper.xml映射文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="renkzu.config.mapper.userMapper">
    <resultMap id="commonResult" type="com.renzku.POJO.SysUser">
        <result column="user_id" property="userId" jdbcType="BIGINT"/>
        <result column="user_name" property="userName" jdbcType="VARCHAR"/>
        <result column="user_text" property="userText" jdbcType="VARCHAR"/>
    </resultMap>

    <select id="findSysUserAllList" resultMap="commonResult">
        SELECT * from myssm_user
    </select>
</mapper>

11.SysUserDaoImpl.java：

　　这里说下，这里配置数据库访问用的SqlSessionDaoSupport。

　　所以在访问时（比如selectList(String namespace [,Object obj])）,至少需要传入mapper.xml的namespace；

　　所以这里的findSysUserAllList()中sqlName变量为 "renzku.config.mapper.userMapper.XX",与userMapper.xml中的namespace一致；

　　就是：

　　1.这个可以随便取名字，只要两处保持相同即可；

　　2.有另外一种配置方式：不用SqlSessionDaoSupport的，只写Dao的 interface，然后跟userMapper.xml关联，这个userMapper.xml就必须写Dao的包路径加文件名称。

package com.renzku.dao.impl;

import com.renzku.POJO.SysUser;
import com.renzku.dao.SysUserDao;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by renzku on 2017/9/9.
 */
@Repository
public class SysUserDaoImpl extends SqlSessionDaoSupport implements SysUserDao {

    @Autowired
    @Override
    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {
        super.setSqlSessionTemplate(sqlSessionTemplate);
    }

    public List<SysUser> findSysUserAllList() {
        String sqlName="renkzu.config.mapper.userMapper"+".findSysUserAllList";
        return this.getSqlSession().selectList(sqlName);
    }
}

12.HelloWorldController.java:

package com.renzku.controller;

import com.renzku.POJO.SysUser;
import com.renzku.service.SysUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

/**
 * Created by renzku on 2017/9/6.
 */
@Controller
public class HelloWorldController {

    @Autowired
    private SysUserService sysUserService;

    @RequestMapping(value = "/helloWorld")
    public String helloWorld(Model model) {
//        直接一直调用到SysUserDaoImpl.findSysUserAllList
        List<SysUser> userlist=this.sysUserService.findSysUserAllList();
        model.addAttribute("ssm", userlist.get(0));
        return "helloWorld";
    }

}

13.helloWorld.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<h2>Hello World!</h2>
<h3>yayaay:${ssm.userName}</h3>

SSM整合配置

SSM三大框架整合详细教程(Spring+SpringMVC+MyBatis) 使用SSM(Spring.SpringMVC和Mybatis)已经有三个多月了,项目在技术上已经没有什么难点了,基于现有的技术就可以实现想要的功能,当然肯定有很多可以改进的地方.之前没有记录SSM整合的过程,这次刚刚好基于自己的一个小项目重新搭建了一次,而且比项目搭建的要更好一些.以前解决问题的过程和方法并没有及时记录,以后在自己的小项目中遇到我再整理分享一下.这次,先说说三大框架整合过程.个人认为使用框架并不是很难

SSM整合shiro

2.3.SSM整合 Shiro 的组件都是 JavaBean/POJO 式的组件,所以非常容易使用 Spring 进行组件管理,可以非常方便的从 ini 配置迁移到 Spring 进行管理,且支持 JavaSE 应用及 Web 应用的集成. 2.3.1.pom文件 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance&

SSM整合框架实现ajax校验

SSM整合框架实现ajax校验 刚学习了ssm框架,ajax校验成功,分享下 1.导入jar包 2.配置spring-servlet.xml 1 <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 2 <property name="messageConverters"> 3 <list> 4 &l

ssm 整合（方案二 maven）

通过maven来整合ssm方便很多,至少不用去找jar包 具体架构如下: 1.配置pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache

SSM- CRUD SSM : SpringMVC+Spring+Mybatis Create (新建) +Retrieve (查询) +Update(更新)+Delete(删除) 功能点 1:分页 2:数据校验:JQuery前端校验+JSR后端校验. 3:ajax 4:Rest风格URL:使用HTTP协议请求方式的动词,来表示对对资源的操作:GET(查询).POST(新增).PUT(修改).DELETE(删除). 技术点 1:基础框架-SSM (SpringMVC+Spring+MyBatis

ssm整合时出现 org.springframework.beans.factory.BeanCreationException ：Error creating bean with name ‘XXX’ 异常的原因及解决方法

ssm整合时出现 org.springframework.beans.factory.BeanCreationException :Error creating bean with name 'XXX' 异常的原因及解决方法(只是可能出现下列几种,不包含全部) 此异常为:注入 bean 失败异常,也就是找不到注入的bean. 可能有以下几种原因: 1.bean未注解或者注解错误 2.项目整合的时候jar包冲突 3.'XXX'的配置有错误 解决:1,3仔细检查就是,网上大部分的人应该是2这种错误,

SSM整合学习笔记

SSM整合核心: 1.持久层: org.mybatis.spring.mapper.MapperScannerConfigurer 自动扫描 将Mapper接口生成代理注入到Spring <!-- 使用mapper批量扫描器扫描mapper接口 规则:mapper.xml和mapper.java在一个目录 且同名即可 扫描出来mapper,自动让spring容器注册,bean的id就是mapper类名(首字母小写) --> <bean class="org.mybatis.sp

ssm 整合中js,css 文件无法引入

问题:ssm 整合中第三方 js,css 文件无法引入 检查:ssm 整合配置完好 无拦截器拦截 spring mvc  静态资源已配置 编译时可以直接跳转到js  css 问题发现 js  css 文件放在WEB-INF 下,导致无法引入 解决 js  css 文件放在webapp 下,可以引入 原文地址:https://www.cnblogs.com/jsbk/p/9461374.html
