SpringMVC+Spring+mybatis 项目实践
SpringMVC+Spring+mybatis 项目实践
1.生成项目
尝试了两种方法,一、利用https://start.spring.io/生成项目解压在,再用IDEA打开
二、是基于maven
注意配置maven的相关信息,前提需要自己安装maven
遇到的问题:项目生成后,IDEA自动下载库失败;
修改了maven 配置的镜像:
镜像代码:
<!-- mirrors | This is a list of mirrors to be used in downloading artifacts from remote repositories. | | It works like this: a POM may declare a repository to use in resolving certain artifacts. | However, this repository may have problems with heavy traffic at times, so people have mirrored | it to several places. | | That repository definition will have a unique id, so we can create a mirror reference for that | repository, to be used as an alternate download site. The mirror site will be the preferred | server for that repository. |--> <mirrors> <!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. | <mirror> <id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url> </mirror> --> <mirror> <id>alimaven</id> <mirrorOf>central</mirrorOf> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/repositories/central/</url> </mirror> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>central</id> <name>Maven Repository Switchboard</name> <url>http://repo1.maven.org/maven2/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>repo2</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://repo2.maven.org/maven2/</url> </mirror> <mirror> <id>ibiblio</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url> </mirror> <mirror> <id>jboss-public-repository-group</id> <mirrorOf>central</mirrorOf> <name>JBoss Public Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> </mirror> <mirror> <id>google-maven-central</id> <name>Google Maven Central</name> <url> https://maven-central.storage.googleapis.com </url> <mirrorOf>central</mirrorOf> </mirror> <!-- 中央仓库在中国的镜像 --> <mirror> <id>maven.net.cn</id> <name>oneof the central mirrors in china</name> <url>http://maven.net.cn/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors>
然后就可以直接下载了。
2.导入相关依赖
3.导入前一个项目的资源
导入后注意修改各类包的引用路径,
4.创建mapper,修改数据库语句,并往所有servlet上添加 @Controller 的注解,转变为Spring MVC。
尝试使用mybatis
(使用mybatis mapper配置失误,数据库连接有问题,最后还是采取以前项目数据库连接)
实现效果:
