MyEclipse Maven Spring Boot mybatis freemarker 配置实例DEMO
1.首先在Myeclipse中新建一个Maven Project项目；本实例中，读取Mysql数据库的数据，在 freemarker模板中显示出来，模板文件在，src/main/resources/templates下的user目录的list.ftl
模板文件代码如下：
id 用户名 密码 邮箱
<#list userList as user>
${user.id} ${user.username} ${user.password} ${user.email}
src/main/resources/mybatis文件夹下UserMapper.xml
2.配置文件application.properties
#datasource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
spring.datasource.username=root
spring.datasource.password=root
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=8081
说明一下，这个文件主要是配置datasource 数据源，和freemarker模板的配置，server.port配置内置服务器的端口8080，（这里测试中不需要外部的服务器，配置好，运行直接就使用Spring Boot内置的服务器测试，很方便）
3.pom.xml 整个项目的配置文件如下：
4.项目的application/application.java 也是程序的入口部分，
package com.lm.application;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.tomcat.jdbc.pool.DataSource;
import org.mybatis.spring.SqlSessionFactoryBean;
import 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要扫描的包
@MapperScan("com.lm.dao")//指定mapper文件所在的包
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
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"));//指定mapper文件所在目录
return sqlSessionFactoryBean.getObject();
}
//创建事务管理器
@Bean
public PlatformTransactionManager transactionManager() {
return new DataSourceTransactionManager(dataSource());
}
}
5.controller/UserController.java 控制类
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
map.addAttribute("userList", userList);
return "/user/list";
}
}
6.dao/UserMapper.java mybatis mapper文件所在的包
package com.lm.dao;
import java.util.List;
import com.lm.model.User;
public interface UserMapper {
List
}
7.model/User.java 模型类
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;
}
}
8.service/UserService.java
package com.lm.service;
import java.util.List;
import com.lm.model.User;
public interface UserService {
List
}
9.sevice/impl/UserServiceImpl.java
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
return userMapper.findAll();
}
}
10.项目文件如下图所示：
11.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：
12.打开浏览器在地址栏输入http://localhost:8081/user/list便可以看到以下效果:
（注意我们在application.properties 中设置了server.port=8081）,你也可以设置其他（80，8080）端口，只要不冲突
