使用idea搭建SSH（idea搭建ssh项目）

使用idea搭建SSH（idea搭建ssh项目）

一、新建项目

  1. 选中Spring

     

     

  2. strust2

     

  3. hibernate

     

二、见项目根路径下的lib下的jar移动到WEB-INF下

  1. 移动

     

  2. 修改路径


  3. 在lib目录下导入【c3p0-0.9.5.2.jar】、【mysql-connector-java-5.1.7-bin.jar】并加载到项目



     

     

三、配置文件

  1. web.xml 
    <?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"

    struts-app.xml、struts-biz.xml、struts-sys.xml....

     

四、新建数据表，并反向映射实体类

  1. 建好数据库表

     

  2. 打开Persistence选项：View→Tool Windows→Persistence

     

  3. 在hibernateGen上右键，进行如下操作

     

  4. 生成

     

  5. 结果

     

报错：java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

  1. 原因：项目未引入【spring-web-5.1.5.RELEASE.jar】
  2. 解决办法：下载【spring-web-5.1.5.RELEASE.jar】

报错：Cannot resolve method ''getContextPath()

  1. 如图

     

  2. 原因：缺少了【javax.servlet-api-3.1.0.jar】和【jsp-api-2.0.jar】

     

配置AOP报错：Could not find bean with name ''org.springframework.aop.support.DefaultBeanFactoryPointcutAdvisor

  • 原因，缺少了包【aopalliance-1.0.jar】和【aspectjweaver-1.9.2.jar】

配置C3P0报错：Error creating bean with name ''dataSource''--Caused by: java.lang.NoClassDefFoundError: com/mchange/v2/ser/Indirector

  • 原因：使用c3p0时要导入两个包【c3p0-0.9.5.2.jar】和【mchange-commons-java-0.2.11.jar】

实体类外键映射报错：Caused by: org.hibernate.MappingException: Repeated column in mapping for entity: com.stureturnlate.moudels.sys.vo.HostelEntity column: dorm_id (should be mapped with insert="false" update="false")

 

 

报错：Caused by: Cannot locate the chosen ObjectFactory implementation: spring - [unknown location]

  1. 在Strust.xml配置了还在报错,缺少整合Struts和Spring的Jar

     

  2. 原因：少了【struts2-spring-plugin-2.5.20.jar】

 启动tomcat报错：java.lang.ClassNotFoundException: org.apache.jsp.index_jsp

  1. 如图：

     

  2. 看看是不是少了这几个包【servlet-api-2.5.jar】和【jsp-api-2.1.jar】和【jstl-1.2.jar】

页面404：strust无法用通配符执行action的方法

  1. 原因：使用了新版本的strust2
  2. 解决办法：在strust2的配置文件中加入【strict-method-invocation="false"】

     

项目中用到JSON,配置struts.xml时遇到json-default发红：Cannot resolve Struts Package ''json-default''

  1. 如图：

     

  2. 原因：缺少了【struts2-json-plugin-2.5.20.jar】

  3. 解决办法：
    一、项目导入包
    二、到Project Structure条件strust配置文件
    三、如下图：

 

SSH框架下Ajax与Action交互数据时报错：org.apache.struts2.json.JSONException: java.lang.reflect.InvocationTargetException

  • 根本原因是：是Hibernate的懒加载引起的。就是在传递的数据中有引用类型的数据采用了懒加载机制。

 

主键(int)查询报错：java.lang.IllegalArgumentException: org.hibernate.TypeMismatchException: Provided id of the wrong type for class com.stureturnlate.moudels.sys.vo.StudentEntity. Expected: class java.lang.String, got class java.lang.Integer

第一种可能：

  •  原因：实体类的hibernate映射文件没有指定字段属性的sql-type，导致查询的时候默认String

     

  • 解决办法：在生成实体类的时候这样子勾选：

第二种可能：

  • 使用了hibernate的get方法查询 
    Session currentSession = sessionFactory.openSession();
return currentSession.get(StudentEntity.class, 主键id);
//return currentSession.load(StudentEntity.class, 主键id);--懒加载查询

     

  • 使用这种方法查询，查询条件必须为主键，且类型要与主键匹配

 

第三种可能：

  • 外键查询
  • 解决办法：（qbc查询） 
    if (studentEntity.getUserId() != null) {

            Criteria cr=currentSession.createCriteria(StudentEntity.class);//userId为student外键，为sysUser主键
//            cr.add(Restrictions.eq("sysUser.userId", studentEntity.getUserId()));//是外键的直接用，没问题
            cr.add(Restrictions.eq("userId", studentEntity.getUserId()));//是外键的直接用，没问题
            //cr.add(Restrictions.eq("sysUser.userName", "aaa"));//报错
//            cr.createAlias("sysUser", "sysUser").add(Restrictions.eq("sysUser.userName", "黄结"));//不是外键的定义别名,不会报错

            list = cr.list();
//            return (StudentEntity) cr.list().get(0);
        } else {

            CriteriaBuilder criteriaBuilder = currentSession.getCriteriaBuilder();

            CriteriaQuery<StudentEntity> query = criteriaBuilder.createQuery(StudentEntity.class);

            Root<StudentEntity> root = query.from(StudentEntity.class);

            Predicate studentId = criteriaBuilder.equal(root.get("studentId"), studentEntity.getStudentId());

            query.where(studentId);

            list = currentSession.createQuery(query).list();

        }
        return list.size()>0&&list!=null?list.get(0):null;
    例子

     

 jsp页面向后台action绑定模型驱动Date类型的属性：No result defined for action com.stureturnlate.moudels.biz.action.student.StudentAction and result input

  • 原因：该实体类的Date属性使用了【java.sql.Date】
  • 解决办法：改为【java.util.Date】

1. intellij idea搭建spring boot项目

1. intellij idea搭建spring boot项目

1.选择Spring Initalizr，JDK选择1.8，点击下一步（如果使用eclipse创建项目请安装STS插件）

2.自己修改 Group 和 Artifact 字段名，点击下一步

  • Name：项目名称
  • Type：我们是Maven构建的，那么选择第一个Maven Project
  • Packaging：打包类型，打包成Jar文件
  • Java Version：jdk版本，选择1.8
  • Language：开发语言，选择Java
  • Group：对应pom文件中的groupId，项目组织的唯一标识，对应Java包的结构
  • Artifact：对应pom文件的artifactId，项目唯一标识，对应项目名称
  • Version：项目版本，对应pom文件的version
  • Description：项目描述，对应pom文件的description
  • Package：包名

3.只要勾选Web下的web就可以了，再选一下spring boot版本号，这里我选择2.0.3，点击下一步

4.填写项目名称，项目存放的目录，点击完成

5.删除无用文件

6.项目结构

Idea搭建servlet开发过程

Idea搭建servlet开发过程

 Idea搭建servlet开发过程

https://www.cnblogs.com/javabg/p/7976977.html

（1）    安装idea，jdk，tomcat；设置好环境变量；

（2）    新建项目工程new-project-java Enterprise-Web Application;

（3）    设置工程名称，也就是程序的根目录；

（4）    创建并设置生成输出目录；在WEB-INF 目录下点击右键，New --> Directory，创建 classes 和 lib 两个目录；File --> Project Structure...，进入 Project Structure窗口，点击 Modules --> 选中项目“JavaWeb” --> 切换到 Paths 选项卡 --> 勾选 “Use module compile output path”，将 “Output path” 和 “Test output path” 都改为之前创建的classes目录；点击 Modules --> 选中项目“JavaWeb” --> 切换到 Dependencies 选项卡 --> 点击右边的“+”，选择 “JARs or directories...”，选择创建的lib目录；

（5）    File --> Project Structure- Artifacts设置打包输出格式和路径；

（6）    Run -> Edit Configurations，进入“Run Configurations”窗口，点击"+"-> Tomcat Server -> Local；配置好tomcat服务器；点击server设置端口；点击deployment设置程序的Application context，这个是本工程的根目录。在浏览器中访问的时候，通过这个路径访问路径WebHello下的类名HelloWorld ，url为http://localhost:8080/WebHello/HelloWorld

（7）    新建Java文件，实现HttpServlet类，实现init接口和destroy接口，重写doGet方法。

import javax.servlet.ServletException; 

import javax.servlet.http.HttpServlet; 

import javax.servlet.http.HttpServletRequest; 

import javax.servlet.http.HttpServletResponse; 

import java.io.IOException; 

import java.io.PrintWriter; 

 

public class HelloWorld extends HttpServlet { 

private String message; 

 

    @Override 

    public void init() throws ServletException { 

    message = "Hello world, this message is from servlet!"; 

    } 

 

    @Override 

    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { 

        //设置响应内容类型 

    resp.setContentType("text/html"); 

 

        //设置逻辑实现 

    PrintWriter out = resp.getWriter(); 

    out.println("<h1>" + message + "</h1>"); 

    } 

 

    @Override 

    public void destroy() { 

    super.destroy(); 

    } 

} 

（8）    配置web.xml文件，在其中添加名称

部署servlet

方法一：

    在WEB-INF目录下web.xml文件的<web-app>标签中添加如下内容：

 <servlet> 

    <servlet-name>HelloWorld</servlet-name> 

    <servlet-class>HelloWorld</servlet-class> 

</servlet>    

<servlet-mapping> 

    <servlet-name>HelloWorld</servlet-name>  根据名称在<servlet>找到servlet-class类HelloWorld

    <url-pattern>/HelloWorld</url-pattern>  //浏览器中输入这个

</servlet-mapping> 

在HelloWorld文件的类前面加上：@WebServlet("/HelloWorld")

（9）    编译运行程序，idea就会将程序部署到tomcat服务器；可以在浏览器中输入http://localhost:8080/HelloWorld

（10）浏览器发送请求，容器接收根据<url-pattern>找到<servlet-name>HelloWorld类名，再由HelloWorld类名找到<servlet-class>HelloWorld，调用接口返回响应。

 

 

 

 

自己编了一个股票监控软件，有如下功能，有兴趣的朋友可以下载；

（1）   个股监测。监测个股实时变化，可以监测个股大单交易、急速拉升和下降、主力入场和出场、股票最高点和最低点提醒。检测到最高点、最低点、主力进场点、主力退场点、急速拉升点、急速下跌点，给出语音或者声音提醒，不用再时刻看着大盘了，给你更多自由的时间；

（2）   大盘监测。监测大盘的走势，采用上证、深证、创业三大指数的综合指数作为大盘走势。并实时监测大盘的最高点和最低点、中间的转折点。

（3）   股票推荐。还能根据历史数据长期或短期走势进行分析，对股市3千多个股票进行分析对比，选出涨势良好的股票，按照增长速度从大到小排序，推荐给你涨势良好的股票；

IDEA搭建spring 5.1.x源码环境

IDEA搭建spring 5.1.x源码环境

1.安装gradle

spring源码是基于gradle构建的，所以首先安装gradle.

下载gradle,地址：https://www.jianshu.com/p/d93...

下载后，在环境变量Path加入bin目录路径

image.png

在命令行中输入gradle -v，有如下信息即OK

image.png

设置grade源为国内源：在.gradle目录下init.gradle文件中加入如下配置，没有init.gradle文件就创建一个

allprojects {
    repositories {
        maven {
            url "http://maven.aliyun.com/nexus/content/groups/public"
        }
    }
}

image.png

2.下载源码

A.spring framework源码

可以直接在github上下载

image.png

从github上下载可能比较慢，下面是网盘资源

链接：https://pan.baidu.com/s/1FpuR...
提取码：18id

B.下载aspectj

3.idea打开源码目录

设置gradel home为gradle的下载目录

image.png

确认ok后，gradle也使用了加速镜像了，还是遇到下载不下来下面的文件，虽然只有27m

Caused by: org.gradle.api.resources.ResourceException: Could not get resource ''https://repo.spring.io/plugins-release/org/jetbrains/kotlin/kotlin-compiler-embeddable/1.2.71/kotlin-compiler-embeddable-1.2.71.jar''.

解决方法：

使用https://www.mvnjar.com/org.je... https://maven.aliyun.com/nexus/content/groups/public/org/jetbrains/kotlin/kotlin-compiler-embeddable/1.2.71/kotlin-compiler-embeddable-1.2.71.jar 下载，

然后将文件拷贝到.gradle目录下cachesmodules-2files-2.1org.jetbrains.kotlinkotlin-compiler-embeddable1.2.71 a79f934bfbc1c7e16638da3474feab351735f1c0目录下即可，a79f934bfbc1c7e16638da3474feab351735f1c0构建的时候生成的目录，然后重新sync

又遇到下面错误,网上查阅资料是我的idea版本太低，gradle版本太高，不匹配，所以降低gradle版本

Cause: org.jetbrains.plugins.gradle.tooling.util.ModuleComponentIdentifierImpl.getModuleIdentifier()Lorg/gradle/api/artifacts/ModuleIdentifier

如下错误

Plugin [id: ''io.spring.dependency-management'', version: ''1.0.7.RELEASE'', apply: false] was not found

取消gradle离线工作模式

如下出现小蓝标说明加载成功
