客户关系管理系统demo

项目分析

该demo使用技术及环境:ssm+maven+bootstrap+jsp+mysql+idea+jdk1.8

需求:客户管理,实现客户列表分页显示如下图

Spring+MyBatis+SpringMvc整合Demo

项目开始

环境搭建

数据库环境:

数据库与表:

客户表

字典表:[设计初衷 -- 将页面很多定义好且无需更改的字符串统一在字典表管理,优化数据库]
pom.xml -- 引入所需jar

思考:整合:ssm+maven+mysql,需要哪些jar?

数据库层:Mysql数据库连接驱动,mybatis相关jar,mybatis与spring整合需要的包

项目初始结构
项目三层建包结构和配置文件

mapper层:

mybatis配置文件[只需提供约束头,里面内容不用写]

mapper配置文件(接口.xml),写sql语句.

spring整合mapper配置文件 spring-mapper.xml

如下:

Spring+MyBatis+SpringMvc整合Demo

需求一:客户列表分页显示

DAO层开发 start

SQL

SELECT

c.cust_id,

c.cust_name,

a.dict_item_name as cust_source,

b.dict_item_name as cust_industry,

d.dict_item_name as cust_level,

c.cust_mobile,

c.cust_phone

FROM

	t_customer c

LEFT OUTER JOIN t_basedict a ON c.cust_source = a.dict_id

LEFT OUTER JOIN t_basedict b ON c.cust_industry = b.dict_id

LEFT OUTER JOIN t_basedict d ON c.cust_level = d.dict_id;

编写sqlMapConfig.xml

<?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">

<configuration>

</configuration>

编写 CustomerMapper接口

分析:

列表显示,且列表需要分页
参数:当前页,每页显示
返回值集合,泛型是QueryVo -- 该类封装客户端列表所需要的数据(客户表和字典表)
sql语句xml相关配置

QueryVo -- POJO类

public class QueryVo {

    private Integer cust_id;

    private String cust_name;

    private String cust_source;  //来源

    private String cust_industry;//行业

    private String cust_level;	 //级别

    private String cust_mobil;

    private String cust_phone;

	private Integer index;//分页开始

	private Integer rows;//数据条数

	//getter and setter method...

}

CustomerMapper中添加方法

	public interface CustomerMapper {

    /**

     * 查询客户列表

     * @param vo 条件对象

     * @return 库户列表

     */

    public List<QueryVo> getCustomerList(QueryVo vo);

}

配置xml

	<?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="com.xingc.example.mapper.CustomerMapper">

	    <select id="getCustomerList" parameterType="com.xingc.example.pojo.QueryVo"

	            resultType="com.xingc.example.pojo.QueryVo">

	        SELECT

	            c.cust_id,

	            c.cust_name,

	            a.dict_item_name AS cust_source,

	            b.dict_item_name AS cust_industry,

	            d.dict_item_name AS cust_level,

	            c.cust_mobile,

	            c.cust_phone

	        FROM

	            t_customer c

	            LEFT OUTER JOIN t_basedict a ON c.cust_source = a.dict_id

	            LEFT OUTER JOIN t_basedict b ON c.cust_industry = b.dict_id

	            LEFT OUTER JOIN t_basedict d ON c.cust_level = d.dict_id

	        <where>

	            <if test="cust_name != null and cust_name != ''">

	                and c.custname LIKE '%${cust_name}%'

	            </if>

	            <if test="cust_source != null and cust_source != ''">

	                and cust_source = #{cust_source}

	            </if>

	            <if test="cust_industry != null and cust_industry != ''">

	                and cust_industry = #{cust_industry}

	            </if>

	            <if test="cust_level != null and cust_level != ''">

	                and cust_level = #{cust_level}

	            </if>

	        </where>

	        limit #{index},#{rows}

	    </select>

	</mapper>

添加db.propertis和log4j.properties配置文件

db.properties:数据库连接的基础配置//数据库,用户名,密码等

log4j.properties:LOG日志所需配置

db.properties

  driverClass=com.mysql.jdbc.Driver

  url=jdbc:mysql:///ssm

  ##注意!!!!!!!!这个user除了username作为变量名外都可以使用,但如果使用username,将会和系统中的username冲突,造成数据库无法连接成功.

  user=root

  password=

log4j.propertis

  ##设置日志记录到控制台的方式

  log4j.appender.s=org.apache.log4j.ConsoleAppender

  log4j.appender.s.Target=System.out

  log4j.appender.s.layout=org.apache.log4j.PatternLayout

  log4j.appender.s.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%L - %m%n

  ##设置日志记录到文件的方式

  log4j.appender.file=org.apache.log4j.FileAppender

  log4j.appender.file.File=mylog.log

  log4j.appender.file.layout=org.apache.log4j.PatternLayout

  log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%L - %m%n

  ##日志输出的级别，以及配置记录方案

  log4j.rootLogger=info, s

编写spring-mapper.xml文件

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <property name="basePackage" value="com.xingc.example.mapper"></property>

    </bean>

</beans>

测试走一波

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {"classpath:spring-mapper.xml"})

public class CustomerMapperTest {

    @Autowired

    private CustomerMapper customerMapper;

    @Test

    public void test(){

        QueryVo vo = new QueryVo();

        vo.setIndex(0);

        vo.setRows(3);

        //查询第一页的三条记录

        List<QueryVo> customerList = customerMapper.getCustomerList(vo);

        System.out.println("\n+++结果数量: "+customerList.size());

        System.out.println("\n+++结果显示: "+customerList);

    }

}

测试结果
至此,mapper测试成功,开发基本完成[单一列表显示功能]

DAO层 end

Service层开发

在service/pom.xml中添加mapper层的jar依赖

编写客户业务逻辑接口

	public interface CustomerService {

	    /**

	     * 查询客户列表

	     * @param vo 条件对象

	     * @return 库户列表

	     */

	    public List<QueryVo> getCustomerList(QueryVo vo);

	}

编写客户业务逻辑实现

//注意:使用该注解的前提是已经配置了 <context:component-scan base-package="com.xingc.example"/>

@Service("customerService")

public class CustomerServiceImpl implements CustomerService {

    @Autowired

    private CustomerMapper customerMapper;

    @Override

    public List<QueryVo> getCustomerList(QueryVo vo) {

        return customerMapper.getCustomerList(vo);

    }

}

测试再来一波

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {"classpath*:spring-*.xml"})

public class CustomerServiceTest {

    @Autowired

    private CustomerService customerService;

    @Test

    public void test() {

        QueryVo vo = new QueryVo();

        vo.setIndex(0);

        vo.setRows(3);

        //查询第一页的三条记录

        List<QueryVo> customerList = customerService.getCustomerList(vo);

        System.out.println("\n+++结果数量: " + customerList.size());

        System.out.println("\n+++结果显示: " + customerList);

    }

}

结果

分页???

由于考虑到前端页面需要对客户列表进行分页,因此这里的业务逻辑需要修改

添加分页实体

  	public class Page<T> {

  		private int total;

  		private int page;

  		private int size;

  	    private List<T> rows;

  		public int getTotal() {

  			return total;

  		}

  		public void setTotal(int total) {

  			this.total = total;

  		}

  		public int getPage() {

  			return page;

  		}

  		public void setPage(int page) {

  			this.page = page;

  		}

  		public int getSize() {

  			return size;

  		}

  		public void setSize(int size) {

  			this.size = size;

  		}

  		public List<T> getRows() {

  			return rows;

  		}

  		public void setRows(List<T> rows) {

  			this.rows = rows;

  		}    

  	}

修改后的实现类和接口

  public interface CustomerService {

      /**

       * 查询客户列表

       * @param vo 条件对象

       * @return 库户列表

       */

      public Page<Customer> getCustomerList(QueryVo vo, Integer page, Integer rows);

  }

实现

  @Service("customerService")

  public class CustomerServiceImpl implements CustomerService {

      @Autowired

      private CustomerMapper customerMapper;

      @Override

      public Page<Customer> getCustomerList(QueryVo vo, Integer page, Integer rows) {

          page = page == null ? page = 1 : page;

          rows = rows == null ? rows = 8 : rows;

          //分页处理

          vo.setIndex((page - 1) * rows);

          vo.setRows(rows);

          //获得数据库查出来的对象

          List<QueryVo> list = customerMapper.getCustomerList(vo);

          //循环封装

          Page p = new Page();

          p.setPage(page);

          p.setSize(rows);

          //总条数

          int total = customerMapper.getCount(vo);

          p.setTotal(total);

          List<Customer> customers = new ArrayList<>();

          Customer customer = null;

          for(QueryVo v : list){

              customer = new Customer();

              customer.setCust_id(v.getCust_id());

              customer.setCust_name(v.getCust_name());

              customer.setCust_source(v.getCust_source());

              customer.setCust_industry(v.getCust_industry());

              customer.setCust_level(v.getCust_level());

              customer.setCust_mobile(v.getCust_mobil());

              customer.setCust_phone(v.getCust_phone());

              customers.add(customer);

          }

          p.setRows(customers);

          return p;

      }

  }

至此,service层开发基本完成,离实现越来越近啦.....

Web层开发开始

到了这里,想说一点,其实实际开发应该不是这样的步骤开发的,应该先把配置文件和项目架构搭起来,再从dao - service - web - 页面依次实现,不过因为我是边写该笔记边开发,因此并未完全按照这个开发步骤来实现.叨逼叨结束...

controller编写

@Controller

@RequestMapping("/cust/")

public class CustomerController {

    @Autowired

    private CustomerService customerService;

    @RequestMapping("/getCustomerList")

    public String getCustomerList(QueryVo vo,Integer page,Integer rows,Model model) {

        Page<Customer> p = customerService.getCustomerList(vo, page, rows);

        model.addAttribute("page",p);

        return "customer";

    }

}

测试

Spring+MyBatis+SpringMvc整合Demo

说明:到这里,ssm配置及基本环境搭建完成,数据成功查出.列表显示后台部分完结,再看一下此时的项目结构

三层架构基本完成,开始前端jsp代码编写

JSP页面编写[jsp+bootstrap]

说明:在这里使用自定义标签的方式定义分页工具栏[和jstl标签是一个道理]

首先,创建jsp自定义标签,步骤如下

定义一个标签类

 /**

  * 显示格式 上一页 1 2 3 4 5 下一页

  */

 public class NavigationTag extends TagSupport {

     static final long serialVersionUID = 2372405317744358833L;

     /**

      * request 中用于保存Page<E> 对象的变量名,默认为“page”

      */

     private String bean = "page";

     /**

      * 分页跳转的url地址,此属性必须

      */

     private String url = null;

     /**

      * 显示页码数量

      */

     private int number = 5;

     @Override

     public int doStartTag() throws JspException {

         JspWriter writer = pageContext.getOut();

         HttpServletRequest request = (HttpServletRequest) pageContext.getRequest();

         Page page = (Page)request.getAttribute(bean);

         if (page == null)

             return SKIP_BODY;

         url = resolveUrl(url, pageContext);

         try {

         	//计算总页数

         	int pageCount = page.getTotal() / page.getSize();

         	if (page.getTotal() % page.getSize() > 0) {

         		pageCount++;

         	}

         	writer.print("<nav><ul class=\"pagination\">");

             //显示“上一页”按钮

         	if (page.getPage() > 1) {

                 String preUrl = append(url, "page", page.getPage() - 1);

                 preUrl = append(preUrl, "rows", page.getSize());

                 writer.print("<li><a href=\"" + preUrl + "\">上一页</a></li>");

             } else {

             }

             //显示当前页码的前2页码和后两页码

             //若1 则 1 2 3 4 5, 若2 则 1 2 3 4 5, 若3 则1 2 3 4 5,

             //若4 则 2 3 4 5 6 ,若10  则 8 9 10 11 12

             int indexPage = (page.getPage() - 2 > 0)? page.getPage() - 2 : 1;

             for(int i=1; i <= number && indexPage <= pageCount; indexPage++, i++) {

                 if(indexPage == page.getPage()) {

创建对应tld文件

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