05-springboot整合beetsql

BeetSql是一个全功能DAO工具， 同时具有Hibernate 优点 & Mybatis优点功能，适用于承认以SQL为中心，同时又需求工具能自动能生成大量常用的SQL的应用。

beetsql优点

• 开发效率
  • 无需注解，自动使用大量内置SQL，轻易完成增删改查功能，节省50%的开发工作量
  • 数据模型支持Pojo，也支持Map/List这种快速模型，也支持混合模型
  • SQL 模板基于Beetl实现，更容易写和调试，以及扩展
• 维护性
  • SQL 以更简洁的方式，Markdown方式集中管理，同时方便程序开发和数据库SQL调试。
  • 可以自动将sql文件映射为dao接口类
  • 灵活直观的支持支持一对一，一对多，多对多关系映射而不引入复杂的OR Mapping概念和技 - 术。
  • 具备Interceptor功能，可以调试，性能诊断SQL，以及扩展其他功能
• 其他
  • 内置支持主从数据库支持的开源工具
  • 支持跨数据库平台，开发者所需工作减少到最小，目前跨数据库支持mysql,postgres,oracle,sqlserver,h2,sqllite,DB2.

添加依赖

在上一节基础上添加如下依赖：

 

    org.springframework.boot
    spring-boot-devtools
    true


    com.ibeetl
    beetl
    2.7.23



    com.ibeetl
    beetlsql
    2.9.12

或

    com.ibeetl
    beetl-framework-starter
    1.1.22.RELEASE

整合阶段

由于springboot没有对 beatlsql的快速启动装配，所以需要我自己导入相关的bean，包括数据源，包扫描，事物管理器等。
在启动类中添加如下代码：

   @Bean(initMethod = "init", name = "beetlConfig")
    public BeetlGroupUtilConfiguration getBeetlGroupUtilConfiguration() {
        BeetlGroupUtilConfiguration beetlGroupUtilConfiguration = new BeetlGroupUtilConfiguration();
        ResourcePatternResolver patternResolver = ResourcePatternUtils.getResourcePatternResolver(new DefaultResourceLoader());
        try {
            // WebAppResourceLoader 配置root路径是关键
            WebAppResourceLoader webAppResourceLoader = new WebAppResourceLoader(patternResolver.getResource("classpath:/templates").getFile().getPath());
            beetlGroupUtilConfiguration.setResourceLoader(webAppResourceLoader);
        } catch (IOException e) {
            e.printStackTrace();
        }
        //读取配置文件信息
        return beetlGroupUtilConfiguration;

    }

    @Bean(name = "beetlViewResolver")
    public BeetlSpringViewResolver getBeetlSpringViewResolver(@Qualifier("beetlConfig") BeetlGroupUtilConfiguration beetlGroupUtilConfiguration) {
        BeetlSpringViewResolver beetlSpringViewResolver = new BeetlSpringViewResolver();
        beetlSpringViewResolver.setContentType("text/html;charset=UTF-8");
        beetlSpringViewResolver.setOrder(0);
        beetlSpringViewResolver.setConfig(beetlGroupUtilConfiguration);
        return beetlSpringViewResolver;
    }

    //配置包扫描
    @Bean(name = "beetlSqlScannerConfigurer")
    public BeetlSqlScannerConfigurer getBeetlSqlScannerConfigurer() {
        BeetlSqlScannerConfigurer conf = new BeetlSqlScannerConfigurer();
        conf.setBasePackage("com.stellar.springboot.bloglearning.beetsql.dao");
        conf.setDaoSuffix("Dao");
        conf.setSqlManagerFactoryBeanName("sqlManagerFactoryBean");
        return conf;
    }

    @Bean(name = "sqlManagerFactoryBean")
    @Primary
    public SqlManagerFactoryBean getSqlManagerFactoryBean(@Qualifier("datasource") DataSource datasource) {
        SqlManagerFactoryBean factory = new SqlManagerFactoryBean();

        BeetlSqlDataSource source = new BeetlSqlDataSource();
        source.setMasterSource(datasource);
        factory.setCs(source);
        factory.setDbStyle(new MySqlStyle());
        factory.setInterceptors(new Interceptor[]{new DebugInterceptor()});
        factory.setNc(new UnderlinedNameConversion());//开启驼峰
        factory.setSqlLoader(new ClasspathLoader("/sql"));//sql文件路径
        return factory;
    }


    //配置数据库
    @Bean(name = "datasource")
    public DataSource getDataSource() {
        return DataSourceBuilder.create().url("jdbc:mysql://127.0.0.1:3306/test").username("root").password("root").build();
    }

    //开启事务
    @Bean(name = "txManager")
    public DataSourceTransactionManager getDataSourceTransactionManager(@Qualifier("datasource") DataSource datasource) {
        DataSourceTransactionManager dsm = new DataSourceTransactionManager();
        dsm.setDataSource(datasource);
        return dsm;
    }

在resouces包下，加META_INF文件夹，文件夹中加入spring-devtools.properties:

restart.include.beetl=/beetl-2.3.2.jar
restart.include.beetlsql=/beetlsql-2.3.1.jar

在templates下加一个index.btl文件。

举个restful的栗子

实体类

public class Account {
    private int id ;
    private String name ;
    private double money;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getMoney() {
        return money;
    }

    public void setMoney(double money) {
        this.money = money;
    }
}

DAO

@SqlResultSetMapping(name="account.md")
public interface BeetSqlAccountDao extends BaseMapper {

    @SqlStatement(params = "name")
    Account selectAccountByName(String name);
}

controller

@RestController
@RequestMapping("/beetsqlAccount")
public class BeetSqlAccountController {

    @Autowired
    BeetSqlAccountDao beetSqlAccountDao;

    @RequestMapping(value = "/list",method = RequestMethod.GET)
    public List getAccounts(){
       return beetSqlAccountDao.all();
    }

    @RequestMapping(value = "/{id}",method = RequestMethod.GET)
    public Account getAccountById(@PathVariable("id") int id){
        return beetSqlAccountDao.unique(id);
    }

    @RequestMapping(value = "",method = RequestMethod.GET)
    public Account getAccountById(@RequestParam("name") String name){
        return beetSqlAccountDao.selectAccountByName(name);
    }

    @RequestMapping(value = "/{id}",method = RequestMethod.PUT)
    public  String updateAccount(@PathVariable("id")int id , @RequestParam(value = "name",required = true)String name,
    @RequestParam(value = "money" ,required = true)double money){
        Account account=new Account();
        account.setMoney(money);
        account.setName(name);
        account.setId(id);
        int t= beetSqlAccountDao.updateById(account);
        if(t==1){
            return account.toString();
        }else {
            return "fail";
        }
    }

    @RequestMapping(value = "",method = RequestMethod.POST)
    public  String postAccount( @RequestParam(value = "name")String name,
                                 @RequestParam(value = "money" )double money) {
        Account account = new Account();
        account.setMoney(money);
        account.setName(name);
        KeyHolder t = beetSqlAccountDao.insertReturnKey(account);
        if (t.getInt() > 0) {
            return account.toString();
        } else {
            return "fail";
        }
    }
}
