1. 创建maven项目
2. 导包

5.使用mybatis的代码生成器创建mapper和domain
6.抽取公共代码
- BaseMapper
package cn.lzj.crm.mapper;
import java.util.List;
public interface BaseMapper<T> {
int deleteByPrimaryKey(Long id);
int insert(T record);
T selectByPrimaryKey(Long id);
List<T> selectAll();
int updateByPrimaryKey(T record);
}
DepartmentMapper 继承BaseMapper
public interface DepartmentMapper extends BaseMapper<Department> {}
- IBaseService
public interface IBaseService<T> {
void save(T department);
void delete(Long id);
void update(T department);
T findOne(Long id);
List<T> findAll();
}
IDepartmentService继承IBaseService
public interface IDepartmentService extends IBaseService<Department>{}
- BaseServiceImpl
package cn.lzj.crm.service.impl;
import cn.lzj.crm.domain.Department;
import cn.lzj.crm.mapper.BaseMapper;
import cn.lzj.crm.mapper.DepartmentMapper;
import cn.lzj.crm.service.IBaseService;
import cn.lzj.crm.service.IDepartmentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
//注意父业务层，不要配置@Service，因为@Service是一个不能被继承的注解
@Transactional(readOnly = true,propagation = Propagation.SUPPORTS)
public class BaseServiceImpl<T> implements IBaseService<T> {
@Autowired
private BaseMapper<T> mapper;
@Override
@Transactional
public void save(T t) {
mapper.insert(t);
}
@Override
@Transactional
public void delete(Long id) {
mapper.deleteByPrimaryKey(id);
}
@Override
@Transactional
public void update(T t) {
mapper.updateByPrimaryKey(t);
}
@Override
public T findOne(Long id) {
return mapper.selectByPrimaryKey(id);
}
@Override
public List<T> findAll() {
return mapper.selectAll();
}
}
DepartmentServiceImpl继承BaseServiceImpl，并实现IDepartmentService
@Service
public class DepartmentServiceImpl extends BaseServiceImpl<Department>
implements IDepartmentService {
}
7.创建controller层，配置Tomcat，测试是否能访问页面内容
到此SSM项目便成功集成
（二）SSM框架集成EasyUI进行CRUD
1.引入EasyUI的js文件
注：此处不需要再将整个easyUI资源全部拷入，只需要拷贝基本功能即可，简约空间，并且提高性能
locale : 国际化支持的文件夹
themes ：主题(eaayui的样式)
jquery.easyui.min.js ： easyui核心的js功能
jquery.min.js ： jQuery的支持
2.上下文路径
idea中配置上下文路径 猫编辑 -> Deployment ->Application context
所有的请求都必需加上这个路径
方案一:在请求前 ： ${pageContext.request.contextPath}
方案二:使用Base标签(推荐，建议在公共jsp内进行添加)
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<base href="<%=basePath%>">
3. 准备common.jsp (/WEB-INF/views/common/common.jsp)
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<base href="<%=basePath%>">
<%--easyui的样式--%>
<link rel="stylesheet" type="text/css" href="easyui/themes/default/easyui.css">
<%--图标样式--%>
<link rel="stylesheet" type="text/css" href="easyui/themes/icon.css">

<%--国际化支持--%>
<script type="text/javascript" src="easyui/locale/easyui-lang-zh_CN.js"></script>
4.department.jsp (/WEB-INF/views/department/department.jsp)
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
<%@ include file="/WEB-INF/views/common/common.jsp"%>

<table cellpadding="5">

5. 准备deparment.js (/static/js/model/department.js)

},
}
depertmentDataGrid.datagrid({
fit:true,
fitColumns:true,
singleSelect:true,
pagination:true,
url:'department/list',
toolbar:'#tools',
columns:[[
{field:'name',title:'名称',width:100},
{field:'id',title:'编号',width:100},
{field:'sn',title:'标识',width:100},
{field:'state',title:'状态',width:100},
]]
});
deptFromDialog.dialog({
title: '编辑',
width: 350,
height: 300,
closed: true,
modal: true,
buttons:'#FromButtons'
});
})
6.分页
- 准备BaseQuery
因为前台使用的是EasyUI框架展示数据，添加分页导航栏之后，刷新数据需要传入的数据是page和rows
public class BaseQuery {
//因为前台使用的是easyUI框架，分页需要的参数是page和rows
private int page;
private int rows = 10; //后台默认显示的数据是10条
//getter与setter省略
}
- DepartmentQuery(如果以后有特殊的查询写在里面)
public class DepartmentQuery extends BaseQuery {
}
- departmentMapper.xml添加分页查询数据的方法
<select id="queryAll" parameterType="DepartmentQuery" resultMap="BaseResultMap" >
select id, sn, name, dirPath, state, manager_id, parent_id
from t_department
</select>
- BaseMapper接口添加分页查询数据的方法
public interface BaseMapper<T> {
//....
Page<T> queryAll(BaseQuery baseQuery);
}
- applicationContext.xml添加分页拦截器
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--配置数据源-->
<property name="dataSource" ref="dataSource" />
<!--配置别名-->
<property name="typeAliasesPackage" value="cn.lzj.crm.domain,cn.lzj.crm.query" />
<!--扫描 mapper.xml-->
<property name="mapperLocations" value="classpath:cn/lzj/crm/mapper/*.xml" />
<!--配置分页拦截器(分页插件):注意版本，不同的版本，配置信息不同，如果没有找到对应的方言，会报空指针异常-->
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<value>helperDialect=mysql</value>
</property>
</bean>
</array>
</property>
</bean>
- service添加分页查询数据的方法
注意：因为EasyUI内，分页查询数据向后台传入的是page和rows参数，但是响应的参数total和rows格式的JSON数据
所以，在后台返回的JSON格式的数据，也需要返回total和rows格式的数据
如果不使用这种返回的数据格式前台只会展示默认显示的10条数据，无法在选择查看其它数据
public class PageResult<T> {
private long total; //总条数
private List<T> rows; //这一行的数据
public PageResult(Page<T> page) {
this.total = page.getTotal();
this.rows = page.getResult();
}
//省略getter和setter方法
}
- BaseServiceImpl中添加方法
//完成分页功能性
@Override
public PageResult<T> queryAll(BaseQuery query) {
//配置分页的值
PageHelper.startPage(query.getPage(),query.getRows());
Page<T> page = mapper.queryAll(query);
return new PageResult<T>(page);
}
- DepartmentController层添加分页的方法
@RequestMapping("/page")
@ResponseBody
public PageResult<Department> queryAll(DepartmentQuery query){
return service.queryAll(query);
}
（三）多模块开发
都没空看开发的目的就是为了实现高内聚、低耦合。利于组件（代码）的重组。

1、模块划分
basic-util:工具(不依赖于其它模块,但是其它模块都要依赖)
basic-core:所有模块的公共代码部分
crm-common:crm这个模块的公共代码部分
crm-mapper:crm这个模块的持久层部分
crm-service:crm这个模块的业务层
crm-web:crm这个模块的web层
2、父项目引入子模块
<?xml version="1.0" encoding="UTF-8"?>
<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.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>cn.lzj</groupId>
<artifactId>maven-many-project</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<!--父模块中引入相应的子模块-->
<modules>
<module>basic-util</module>
<module>oa-service</module>
</modules>
</project>
3、子模块中引入其它子模块
在其他子模块的pom.xml中
<!--加一个依赖：座标就可以引入相应的模块功能-->
<dependencies>
<dependency>
<groupId>cn.lzj</groupId>
<artifactId>basic-util</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
