MAVEN_SPRING+SPRINGMVC+MYBATIS+FREEMARKER 整合

其他 2018-05-08 09:18:58 阅读次数: 3

          在公司实习的时候 公司用的是  MAVEN_SPRING+SPRINGMVC+MYBATIS+FREEMARKER 框架； 用了2个月；就想自己来整合一下框架；


一：

在整合的时候我也参考了很多博文；但是都不一样，比如配置文件，我就不知道怎么样子分才好；有人分2个，有人分3个之类的；这里我分了两个配置文件

一个是；spring-mvc.xml   这个就专门用来配置springmvc的；  一个是spring-mybatis.xml；用来整合spring和mybatis；

       整体如下：


二,maven引入相应的jar包；

三、整合Spring与MyBatis 

 这个文件就是用来完成spring和mybatis的整合的。这里面也没多少行配置，主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。

spring-mybatis.xml  

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

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

	<!-- 自动扫描mapping.xml文件 -->

	</bean>
	
  <!-- DAO接口所在包名，Spring会自动查找其下的类 -->

四、 Log4j的配置

 为了方便调试，一般都会使用日志来输出信息，Log4j是Apache的一个开放源代码项目，通过使用Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI组件，甚至是套接口服务器、NT的事件记录器、UNIX Syslog守护进程等；我们也可以控制每一条日志的输出格式；通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。

      Log4j的配置很简单，而且也是通用的，下面给出一个基本的配置，换到其他项目中也无需做多大的调整，如果想做调整或者想了解Log4j的各种配置，参看我转载的一篇博文，很详细：

http://blog.csdn.net/zhshulin/article/details/37937365

下面给出配置文件目录：

log4j.properties

[html] view plaincopyprint?在CODE上查看代码片派生到我的代码片
#定义LOG输出级别  
log4j.rootLogger=INFO,Console,File  
#定义日志输出目的地为控制台  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
#可以灵活地指定日志输出格式，下面一行是指定具体的格式  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  
  
#文件大小到达指定尺寸的时候产生一个新的文件  
log4j.appender.File = org.apache.log4j.RollingFileAppender  
#指定输出目录  
log4j.appender.File.File = logs/ssm.log  
#定义文件最大大小  
log4j.appender.File.MaxFileSize = 10MB  
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志  
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n



五、

利用MyBatis Generator自动创建代码

参考博文：http://blog.csdn.net/zhshulin/article/details/23912615




mapper.xml生成的文件；

<?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="com.szz.dao.IAdditionalDao" >

  </sql>
  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer" >
    select 
    <include refid="Base_Column_List" />
    from additional
    where ID = #{id,jdbcType=INTEGER}
  </select>
  
 <!-- 自己添加的 -->
  <sql id="find_condition" >
  	<if test="condition !=null">
  	  <if test="condition.id != null" >
        and ID=#{condition.id}
      </if>
      <if test="condition.emplid != null" >
         and EmplID=#{condition.emplid}
      </if>

       and Totalincome=#{condition.totalincome}
      </if>
      <if test="condition.percent != null" >
       and percent=#{condition.percent}
      </if>
      <if test="condition.totalearn != null" >
       and TotalEarn=#{condition.totalearn}
      </if>
      <if test="condition.remark != null" >
       and remark=#{condition.remark}
      </if>
     </if> 
  </sql>
  
  <select id="find" resultMap="BaseResultMap" parameterType="java.util.Map" >
  		select * from additional 
  		 <trim prefix="WHERE" prefixOverrides="AND">
  		   <include refid="find_condition" />
  		   </trim>
  </select>
  
  <!-- end  自己添加的 -->
  <delete id="deleteByPrimaryKey" parameterType="java.lang.Integer" >
    delete from additional
    where ID = #{id,jdbcType=INTEGER}
  </delete>
  <insert id="insert" parameterType="com.szz.model.Additional" >
    insert into additional (ID, EmplID, Totalincome, 
      percent, TotalEarn, remark
      )
    values (#{id,jdbcType=INTEGER}, #{emplid,jdbcType=INTEGER}, #{totalincome,jdbcType=DECIMAL}, 
      #{percent,jdbcType=REAL}, #{totalearn,jdbcType=DECIMAL}, #{remark,jdbcType=VARCHAR}
      )
  </insert>
  <insert id="insertSelective" parameterType="com.szz.model.Additional" >
    insert into additional
    <trim prefix="(" suffix=")" suffixOverrides="," >
      <if test="id != null" >
        ID,
      </if>
      <if test="emplid != null" >
        EmplID,
      </if>
      <if test="totalincome != null" >
        Totalincome,
      </if>
      <if test="percent != null" >
        percent,
      </if>
      <if test="totalearn != null" >
        TotalEarn,
      </if>
      <if test="remark != null" >
        remark,
      </if>
    </trim>
    <trim prefix="values (" suffix=")" suffixOverrides="," >
      <if test="id != null" >
        #{id,jdbcType=INTEGER},
      </if>
      <if test="emplid != null" >
        #{emplid,jdbcType=INTEGER},
      </if>
      <if test="totalincome != null" >
        #{totalincome,jdbcType=DECIMAL},
      </if>
      <if test="percent != null" >
        #{percent,jdbcType=REAL},
      </if>
      <if test="totalearn != null" >
        #{totalearn,jdbcType=DECIMAL},
      </if>
      <if test="remark != null" >
        #{remark,jdbcType=VARCHAR},
      </if>
    </trim>
  </insert>
  <update id="updateByPrimaryKeySelective" parameterType="com.szz.model.Additional" >
    update additional
    <set >
      <if test="emplid != null" >
        EmplID = #{emplid,jdbcType=INTEGER},
      </if>
      <if test="totalincome != null" >
        Totalincome = #{totalincome,jdbcType=DECIMAL},
      </if>
      <if test="percent != null" >
        percent = #{percent,jdbcType=REAL},
      </if>
      <if test="totalearn != null" >
        TotalEarn = #{totalearn,jdbcType=DECIMAL},
      </if>
      <if test="remark != null" >
        remark = #{remark,jdbcType=VARCHAR},
      </if>
    </set>
    where ID = #{id,jdbcType=INTEGER}
  </update>
  <update id="updateByPrimaryKey" parameterType="com.szz.model.Additional" >
    update additional
    set EmplID = #{emplid,jdbcType=INTEGER},
      Totalincome = #{totalincome,jdbcType=DECIMAL},
      percent = #{percent,jdbcType=REAL},
      TotalEarn = #{totalearn,jdbcType=DECIMAL},
      remark = #{remark,jdbcType=VARCHAR}
    where ID = #{id,jdbcType=INTEGER}
  </update>
</mapper>

自动生成的mapper.xml文件大部分能满足增删改查的要求；  但是查询只给了一个select  by primarykey   ；只能查询一条数据；   我自己写了一个多条件查询的；但是我不知道怎么修改   

MyBatis Generator  让它也自动生成我添加的代码； 等以后有空研究下； 有知道怎么修改的能否告知一二；



六、测试一下； 

public interface DepartmentService {


<span style="white-space:pre">	</span>//这里没有写全；  就写了2个方法；
	List<Department> find(DepartmentVO condition);
	Department get(Integer id);
}


@Service("departmentImplService")
public class DepartmentImplService implements DepartmentService{
	
	@Resource
	private IDepartmentDao departmentDAO;
	@Override
	public List<Department> find(DepartmentVO condition) {
		// TODO Auto-generated method stub
		/*HashMap<String,Object> param = new HashMap<String,Object>();*/
		Map<String,Object> params = Maps.newHashMap();
		params.put("condition", condition);
		return departmentDAO.find(params);
	}
	@Override
	public Department get(Integer id) {
		// TODO Auto-generated method stub
		return departmentDAO.selectByPrimaryKey(id);
	}

}


//VO是继承model的    方便添加查询条件； 
@Controller
@RequestMapping("/department")
public class DepartmentController {

	@Resource 
	private DepartmentImplService departmentService;
	
	@RequestMapping("/index")
	public String index(Model model){
		Department dp = departmentService.get(1);
		DepartmentVO condition = new DepartmentVO();
		condition.setStatus("1");
		List<Department> dep = departmentService.find(condition);
		model.addAttribute("dp_name", dep.get(0).getDpName());
		return "/test";
	}
}


<html>
<head>
<title>hello!</title>
</head>
<body>
.........
<h1>hello ${dp_name}</h1>
</body>
</html>

运行



完成！！


继续整合freemarker；

只需要在spring-mvc.xml 

<bean id="freemarkerSettings" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name="location" value="classpath:freemarker.properties" />
  </bean>

  <bean id="freemarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
    <property name="freemarkerSettings" ref="freemarkerSettings" />
    <property name="templateLoaderPath" value="/WEB-INF/view/" />
  </bean>

  <bean id="freemarkerViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
    <property name="contentType" value="text/html; charset=UTF-8" />
    <property name="suffix" value=".ftl" />
    <property name="exposeRequestAttributes" value="true" />
    <property name="requestContextAttribute" value="request" />
  </bean>

  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  </bean>

并且maven的pom文件中引入freemarker的jar就行了 

 <dependency>
			<groupId>org.freemarker</groupId>
			<artifactId>freemarker</artifactId>
			 <version>2.3.20</version>
		</dependency>



整合完成了！！
