Spring Boot实践应用开发（6）

【使用thymeleaf生成html页面】

1,新建mybatissql文自动生成配置文件，generateConfig_sample.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration PUBLIC
"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >
<generatorConfiguration>
<classPathEntry
location="E:/pleiades/workspace/sample/src/main/resources/lib/ojdbc6.jar" />
<context id="context1">
<jdbcConnection driverClass="oracle.jdbc.OracleDriver"
connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:orcl" userId="sample"
password="sample" />

<javaModelGenerator targetPackage="org.com.sample.dataset"
targetProject="sample" />
<sqlMapGenerator targetPackage="org.com.sample.mapper"
targetProject="sample" />
<javaClientGenerator targetPackage="org.com.sample.mapper"
targetProject="sample" type="XMLMAPPER" />

<table tableName="Users" />

</context>
</generatorConfiguration>

2,自动生成dataset，mapper等相关文件。

sample
|_src/main/java
|_org.com.sample
|_dataset
|_Users.java
|_UserExample.java
|_mapper
|_UsersMapper.java
|_UsersMapper.xml

把UsersMapper.xml移动到resources文件夹下

|_src/main/resources
|_org.com.sample
|_mapper
|_UsersMapper.java

3,在ApplicationConfig.java里，定义Mapper的bean

<pre name="code" class="java">Resource[] resources = new Resource[] { getMapperXMLPathResource(UsersMapper.class)
};

@Bean
public UsersMapper getUsersMapper() {
SqlSessionTemplate sessionTemplate = new SqlSessionTemplate(getSqlSessionFactory());
return sessionTemplate.getMapper(UsersMapper.class);
}

4，新规UsersService接口，内容和UsersMapper一样。

package org.com.sample.service;

import java.util.List;
import org.apache.ibatis.annotations.Param;
import org.com.sample.dataset.Users;
import org.com.sample.dataset.UsersExample;

public interface UsersService {
/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int countByExample(UsersExample example);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int deleteByExample(UsersExample example);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int deleteByPrimaryKey(String username);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int insert(Users record);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int insertSelective(Users record);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
List<Users> selectByExample(UsersExample example);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
Users selectByPrimaryKey(String username);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int updateByExampleSelective(@Param("record") Users record, @Param("example") UsersExample example);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int updateByExample(@Param("record") Users record, @Param("example") UsersExample example);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int updateByPrimaryKeySelective(Users record);

/**
* This method was generated by MyBatis Generator.
* This method corresponds to the database table USERS
*
* @mbggenerated Sat Oct 10 16:15:21 JST 2015
*/
int updateByPrimaryKey(Users record);
}

5，新规UsersService的实现类，UsersServiceImpl.java

package org.com.sample.service.impl;

import java.util.List;

import org.com.sample.dataset.Users;
import org.com.sample.dataset.UsersExample;
import org.com.sample.mapper.UsersMapper;
import org.com.sample.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UsersServiceImpl implements UsersService {

@Autowired
UsersMapper usersMapper;

@Override
public int countByExample(UsersExample example) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int deleteByExample(UsersExample example) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int deleteByPrimaryKey(String username) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int insert(Users record) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int insertSelective(Users record) {
// TODO Auto-generated method stub
return 0;
}

@Override
public List<Users> selectByExample(UsersExample example) {

return usersMapper.selectByExample(example);
}

@Override
public Users selectByPrimaryKey(String username) {
// TODO Auto-generated method stub
return null;
}

@Override
public int updateByExampleSelective(Users record, UsersExample example) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int updateByExample(Users record, UsersExample example) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int updateByPrimaryKeySelective(Users record) {
// TODO Auto-generated method stub
return 0;
}

@Override
public int updateByPrimaryKey(Users record) {
// TODO Auto-generated method stub
return 0;
}

}

6,新规UsersFacade接口

package org.com.sample.facade;

import java.util.List;

import org.com.sample.dataset.Users;
import org.com.sample.dataset.UsersExample;

public interface UsersFacade {

List<Users> selectByExample(UsersExample example);
}

7，新规UsersFacade接口的实现类，UsersFacadeImpl.java

package org.com.sample.facade.impl;

import java.util.List;

import org.com.sample.dataset.Users;
import org.com.sample.dataset.UsersExample;
import org.com.sample.facade.UsersFacade;
import org.com.sample.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class UsersFacadeImpl implements UsersFacade {

@Autowired
UsersService usersService;

@Override
public List<Users> selectByExample(UsersExample example) {

return usersService.selectByExample(example);
}

}

8,新规UsersController.java

package org.com.sample.controller;

import java.util.List;

import org.com.sample.dataset.Users;
import org.com.sample.dataset.UsersExample;
import org.com.sample.facade.UsersFacade;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/sample/users")
public class UsersController {

private static final Logger logger = LoggerFactory.getLogger(UsersController.class);

@Autowired
UsersFacade userFacade;

@RequestMapping(value = "/show", method = RequestMethod.GET)
public String selectAllUser(Model model) {

List<Users> userList = userFacade.selectByExample(new UsersExample());
model.addAttribute("page", userList);
return "sample/users/users";
}

}

9,新规users.html

<head>
<meta charset="UTF-8" />
