标签:null pen error 元素 联系方式 classpath 新建 display 问题





去泡一杯咖啡吧,这里需要一小段时间哦~

新建好项目后,我们首先打开SSM_Demo,修改一下JDK版本。


在settings里面对项目版本进行修改:

原来是1_5,现在改为1_8,可能会存在spring等框架版本和jdk版本不兼容问题,因此,提前升级了版本。

220 </project>

在其中添加下面配置标签信息:
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans 7 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 8 http://www.springframework.org/schema/context 9 http://www.springframework.org/schema/context/spring-context-3.1.xsd 10 http://www.springframework.org/schema/mvc 11 http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> 12 13 <!-- 启动注解驱动的Spring MVC功能,注册请求url和注解POJO类方法的映射--> 14 <mvc:annotation-driven > 15 16 </mvc:annotation-driven> 17 18 <!-- 启动包扫描功能,以便注册带有@Controllers、@service、@repository、@Component等注解的类成为spring的bean --> 19 <context:component-scan base-package="Controllers" /> 20 <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 --> 21 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 22 <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> 23 <property name="prefix" value="/"/> <!-- 前缀 --> 24 <property name="suffix" value=".jsp"/> <!-- 后缀 --> 25 </bean> 26 <!-- 访问静态文件(jpg,js,css)的方法 --> 27 <!--<mvc:resources location="/files/" mapping="/files/**" />--> 28 <!--<mvc:resources location="/scripts/" mapping="/scripts/**" />--> 29 <!--<mvc:resources location="/styles/" mapping="/styles/**" />--> 30 <!--<mvc:resources location="/Views/" mapping="/Views/**" />--> 31 </beans>

这里的Controllers对应的是我们之前新建好的Controllers包文件夹。


这里的classpath为resources资源目录
1 <!DOCTYPE web-app PUBLIC 2 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" 3 "http://java.sun.com/dtd/web-app_2_3.dtd" > 4 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 5 xmlns="http://java.sun.com/xml/ns/javaee" 6 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 7 version="3.0"> 8 <display-name>Archetype Created Web Application</display-name> 9 <welcome-file-list> 10 <welcome-file>/index.jsp</welcome-file> 11 </welcome-file-list> 12 <!-- Spring MVC配置 --> 13 <servlet> 14 <servlet-name>spring</servlet-name> 15 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 16 <!--Spring-servlet.xml config--> 17 <init-param> 18 <param-name>contextConfigLocation</param-name> 19 <param-value>classpath:spring-servlet.xml</param-value> 20 </init-param> 21 <!-- load-on-startup元素标记容器是否在启动的时候就加载这个servlet(实例化并调用其init()方法) --> 22 <load-on-startup>1</load-on-startup> 23 </servlet> 24 <servlet-mapping> 25 <servlet-name>spring</servlet-name> 26 <url-pattern>/</url-pattern> 27 </servlet-mapping> 28 </web-app>

接下来在RequestTestController里面写一个rest api接口:

接口代码如下:
1 package Controllers;
2
3 import org.springframework.web.bind.annotation.GetMapping;
4 import org.springframework.web.bind.annotation.RequestMapping;
5 import org.springframework.web.bind.annotation.RestController;
6
7 @RestController
8 @RequestMapping("/api/RequestTest")
9 public class RequestTestController {
10
11 @GetMapping()
12 public String TestString(){
13 return "this is a test string. Time:2017-10-29 20:42:00";
14 }
15 }
这样,我们便可以通过url地址来进行访问我们的接口数据

在右上角的运行服务器配置按钮,打开服务器配置项

这里如果左侧列表是空的话,我们就需要点击加号进行服务器的添加,选择Tomcat Server下的Local。然后点击刚刚添加的标签,在右侧输入Server Name,下面会自动提示设置编译方式,选一个编译方式,然后点击OK即可(这一步的前提是装好了Tomcat服务器,如果没有安装,则需要先安装Tomcat服务器)。
然后我们点击右上角的运行,如果没有什么问题的话,我们的控制台界面会提示服务启动成功!(我这样下来是不会出问题的)

等浏览器打开以后,我们输入我们配置的api地址:http://localhost:8080/api/RequestTest

这样,spring mvc已经成功整合到了项目里面!
稍歇片刻后,我们继续进行Mybatis和Spring组件的整合...

内容如下:
jdbc.properties内容如下:
spring-mybatis.xml内容如下:
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans 3 xmlns="http://www.springframework.org/schema/beans" 4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 7 8 <context:annotation-config /> 9 <!-- 配置component所在的包,自动加载需要管理的Bean --> 10 <context:component-scan base-package="Service,Dao" /> 11 <import resource="spring-mybatis.xml" /> 12 </beans>
applicationContext.xml配置文件是对spring的配置,我们配置spring组件的扫描包围Service和Dao层目录,然后将spring-mybatis.xml配置文件导入.
完成这三个后的文件目录是这样子的:

target文件夹是刚才编译运行时候自动产生的,不要惊慌~~~
在刚才的web-app标签内继续添加spring支持:

此刻完整的web.xml文件内容如下:
web.xml到此刻,我们的spring、mybatis已经整合完毕,接下来稍歇片刻,我们进行demo的完成。
打开数据库,我们新建一个数据库,并设计两张测试表,student和studentclass

student表的设计如下:

-- ---------------------------- -- Table structure for `student` -- ---------------------------- DROP TABLE IF EXISTS `student`; CREATE TABLE `student` ( `Uid` binary(36) NOT NULL COMMENT ‘Uid‘, `Name` varchar(20) NOT NULL, `Age` int(3) NOT NULL, `ClassId` int(3) NOT NULL, PRIMARY KEY (`Uid`), KEY `StudentClass` (`ClassId`), CONSTRAINT `StudentClass` FOREIGN KEY (`ClassId`) REFERENCES `studentclass` (`ClassId`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
studentclass表的设计如下:

-- ---------------------------- -- Table structure for `studentclass` -- ---------------------------- DROP TABLE IF EXISTS `studentclass`; CREATE TABLE `studentclass` ( `ClassId` int(3) NOT NULL AUTO_INCREMENT, `ClassName` varchar(10) DEFAULT NULL, PRIMARY KEY (`ClassId`) ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
将数据库建好后,我们进行Entity,Dao,Service层以及mapper文件的的编写。
1 <?xml version="1.0" encoding="UTF-8"?>
2 <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

以上这段代码是直接使用mybatis generator直接进行生成的,如果不想手写的话(手写容易出错),可以直接使用该工具进行生成,该工具的下载以及使用参见本人博客地址:http://www.cnblogs.com/qixiaoyizhan/p/7597315.html

17
18 List<Student> selectByCondition(Student record);
19
20 int updateByPrimaryKeySelective(Student record);
21

IStudentService 接口:
1 package Service;

3 import Entity.Student;
4
5 import java.util.List;
6
7 public interface IStudentService {
8 int deleteByPrimaryKey(byte[] uid);

43 }
44
45 @Override
46 public int updateByPrimaryKey(Student record) {

48 }
49 }

20 List<Student> students = service.selectByCondition(new Student());
21 String jsonResult = com.alibaba.fastjson.JSON.toJSONString(students);
22 return jsonResult;
23 }
24 }
走到这一步的代码目录结构是这样子的:

运行时候,别忘记了修改jdbc.properties文件里的连接url以及用户名密码!!!


哇,数据成功显示!(别把这个数据当成你会真的显示出来的一样,这是我数据库原有的数据,哈哈哈)

还不快去添加几条数据调用一下试试嘛~
至此,我们的SSM框架已经基本搭建完毕,我们已经用我们搭建的Demo从真实的数据库中获取到了数据,并转成了Json格式,在浏览器中用Rest api接口的形式获取到了。
该项目源代码可以在Github上找到,如果需要的可以直接去下载->
https://github.com/dong666/SSM-Demo (不赶紧访问点个Star嘛?)
如果在搭建中还有任何疑问,随时可以在下面的签名联系方式中找到我~ 茫茫人海中,也是有缘~~~
如果有推荐工作的也可以在下面的联系方式中找到我哦,如果是这样的话,我是真的感激呢!!!~~~
