搭建了数次的springmvc框架了
但是每次重新搭建都要花费很多的时间
这次决心要记录下来是为了提高效率
后续会不断的在此基础上不断的更新文章，
此次用到的有maven jdk8
点击右键新增maven-project,选择webapp
项目右键点击properties java build path 将maven和jre选中确定
pom.xml文件中添加
<build>
<finalName>springmvc</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
这样会防止maven在update的时候将jdk1.8变为1.5或1.6
src/main/resources下面新建两个xml文件，spring.xml,和spring-mvc.xml
spring.xml配置主要是自动扫描
<?xml version="1.0" encoding="UTF-8"?>

</beans>
此时需要在web.xml中引入这两个文件
<?xml version="1.0" encoding="UTF-8"?>

测试
新建一个interface
package com.xxxx.repo;
public interface IUserService {
public String getName(String name);
}
实现类，注意加入注解
package com.xxxx.repo.impl;
import org.springframework.stereotype.Service;
import com.xxxx.repo.IUserService;
@Service("userService")
public class UserServiceImpl implements IUserService {
public String getName(String name) {
return name;
}
}
控制层 注意加入映射与注解
package com.xxxx.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.xxxx.repo.IUserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource
private IUserService userService;
@RequestMapping("/getname")
@ResponseBody
public String getName() {
return userService.getName("离散");
}
}
使用tomcat运行(emmm发现运行起来了 但是找不到页面)
还是用jetty吧，，
直接右键 run jetty
浏览器输入（此处我自己把端口设置了8089）
http://127.0.0.1:8089/springmvc/user/getname
emm乱码了。。但是通了 ，乱码下一篇文章再说吧。。88
