详解MyEclipse中搭建spring

详解MyEclipse中搭建spring

1.在MyEclipse里创建一个maven项目。File>New>Maven Project：

勾选图中红色部分，然后点击Next。

2.填写下图中红色部分然后点击Finish。

3.此时一个maven项目已经生成，目录结构如下：

4.打开pom.xml在里面编辑如下内容：

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

5.创建程序入口Application.java.

package com.lm.application;

import org.apache.ibatis.session.SqlSessionFactory;

import org.apache.tomcat.jdbc.pool.DataSource;

import org.mybatis.spring.SqlSessionFactoryBean;

imphttp://ort org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import org.springframework.transaction.PlatformTransactionManager;

@EnableAutoConfiguration

@SpringBootApplication

@ComponentScan(basePackages={"com.lm"})//指定spring管理的bean所在的包

@MapperScan("com.lm.dao")//指定mybatis的mapper接口所在的包

public class Application{

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}

//创建数据源

@Bean

@ConfigurationProperties(prefix = "spring.datasource")//指定数据源的前缀 ,在application.properties文件中指定

public DataSource dataSource() {

return new DataSource();

}

//创建SqlSessionFactory

@Bean

public SqlSessionFactory sqlSessionFactoryBean() throws Exception {

SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();

sqlSessionFactoryBean.setDataSource(dataSource());

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis/*.xml"));

return sqlSessionFactoryBean.getObject();

}

//创建事物管理器

@Bean

public PlatformTransactionManager transactionManager() {

return new DataSourceTransactionManager(dataSource());

}

}

6.在src/main/resources下建立应用的配置文件application.properties。

#datasource

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/你的数据库名称?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull

spring.datasource.username=数据库用户名

spring.datasource.password=数据库密码

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

# FREEMARKER (FreeMarkerAutoConfiguration)

spring.freemarker.allow-request-override=false

spring.freemarker.allow-session-override=false

spring.freemarker.cache=true

spring.freemarker.charset=UTF-8

spring.freemarker.check-template-location=true

spring.freemarker.content-type=text/html

spring.freemarker.enabled=true

spring.freemarker.expose-request-attributes=false

spring.freemarker.expose-session-attributes=false

spring.freemarker.expose-spring-macro-helpers=true

spring.freemarker.prefer-file-system-access=true

spring.freemarker.suffix=.ftl

spring.freemarker.template-loader-path=classpath:/templates/

spring.freemarker.settings.template_update_delay=0

spring.freemarker.settings.default_encoding=UTF-8

spring.freemarker.settings.classic_compatible=true

spring.freemarker.order=1

#server

server.port=80

相应的配置需要根据自己的实际情况去做修改。

7.在在src/main/resources下创建mybatis目录并在目录下创建UserMapper.xml文件：

select id, username,password,email from t_user

8.创建UserController类和视图文件：

package com.lm.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.web.bind.annotation.RequestMapping;

import com.lm.model.User;

import com.lm.service.UserService;

@Controller

@RequestMapping("/user")

public class UserController {

@Autowired

private UserService userService;

@RequestMapping("/list")

public String list(ModelMap map){

List userList=userService.findAll();

map.addAttribute("userList", userList);

return "/user/list";

}

}

可以看出list方法返回的是一个字符串，因为我们给应用加载了freemarker模块做视图展现，所以需要创建一个list模板，模板所在的目录在application.properties中指定为spring.freemarker.template-loader-path=classpath:/templates/，所以我们需要在src/main/resources下创建templates目录，然后在templates下创建user目录，模板文件后缀在application.properties中指定为spring.freemarker.suffix=.ftl，所以最终建立一个list.ftl文件:

<#list userList as user>

#list>

模板文件所在位置的目录结构如下图:

9.创建UserService接口:

package com.lm.service;

import java.util.List;

import com.lm.model.User;

public interface UserService {

List findAll();

}

10.创建UserServiceImpl类实现UserService接口:

package com.lm.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import com.lm.dao.UserMapper;

import com.lm.model.User;

import com.lm.service.UserService;

@Service

public class UserServiceImpl implements UserService{

@Autowired

private UserMapper userMapper;

@Override

public List findAll() {

return userMapper.finhttp://dAll();

}

}

11.创建UserMapper接口:

package com.lm.dao;

import java.util.List;

import com.lm.model.User;

public interface UserMapper {

List findAll();

}

12.创建实体类User:

package com.lm.model;

public class User {

private Integer id;

private String username;

private String password;

private String email;

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getUsername() {

return username;

}

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

}

13.至此spring-boot框架已搭建完成，然后在Application.java中run as >java application此时在控制台会看到如下日志输出：

14.打开浏览器在地址栏输入http://localhost/user/list便可以看到以下效果:

15.在pom.xml文件上右键Run As>Maven install可将项目打包为jar文件，生成的jar在target目录下，可以将此jar拷贝到服务器上通过"java -jar 最终生成jar包的名字"运行项目。

16.本项目的源码已经上传到spring-boot_jb51.rar，有需要的朋友可以自行下载
