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application加入以下代码:

@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.forezp.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("123456").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。

加入jar和配置beatlsql的这些bean,以及resources这些配置之后,springboot就能够访问到数据库类。

举个restful的栗子

初始化数据库的表

DROP TABLE account IF EXISTS

CREATE TABLE account ( id int(11) NOT NULL AUTO_INCREMENT, name varchar(20) NOT NULL, money double DEFAULT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8; INSERT INTO account VALUES ('1', 'aaa', '1000'); INSERT INTO account VALUES ('2', 'bbb', '1000'); INSERT INTO account VALUES ('3', 'ccc', '1000'); bean

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

getter...

setter...

}
数据访问dao层

public interface AccountDao extends BaseMapper {

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

} 接口继承BaseMapper,就能获取单表查询的一些性质,当你需要自定义sql的时候,只需要在resouses/sql/account.md文件下书写文件:

selectAccountByName

*根据name获account

select * from account where name= #name#

其中“=== ”上面是唯一标识,对应于接口的方法名,“* ”后面是注释,在下面就是自定义的sql语句,具体的见官方文档。

web层

这里省略了service层,实际开发补上。

@RestController @RequestMapping("/account") public class AccountController {

@Autowired
AccountDao accountDao;

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

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

@RequestMapping(value = "",method = RequestMethod.GET)
public  Account getAccountById(@RequestParam("name") String name){
    return accountDao.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=accountDao.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 = accountDao.insertReturnKey(account);
    if (t.getInt() > 0) {
        return account.toString();
    } else {
        return "fail";
    }
}

通过postman 测试,代码已全部通过。
