HttpNetty

我不想用Struts2绝不是因为它有漏洞，因为我自己写的漏洞更多......

👉Blog

技术特点

1.使用Netty作为http服务器
2.支持注解@Controller、@RequestMapping等
3.利用maven项目管理
4.简洁的请求数据提取
6.HikariCP连接池
7.依赖注入（反射实现）

注解@Controller、@RequestMapping

@Controller(path = "/index")
publicclassIndexController {
@RequestMapping(method = RequestMethod.POST, path = "/test")
publicStringtest(Map<String, Object> map) {
returnJSONObject.toJSONString(map);
}
}

Http Netty : 2020-05-09 04:34:34 GET -> /
Http Netty : 2020-05-09 04:34:34 GET -> /static/css
Http Netty : 2020-05-09 04:34:34 GET -> /static/js
Http Netty : 2020-05-09 04:34:34 GET -> /static/img
Http Netty : 2020-05-09 04:35:30 POST -> /index/test

请求数据提取

• 将GET、PUOST、PUT、DELETE请求数据统一解析成Map,无论是application/x-www-form-urlencoded、multipart/form-data还是application/json

解析 application/x-www-form-urlencoded、application/json等

@RequestMapping(method = RequestMethod.POST, path = "/test")
publicStringtest(Map<String, Object> map) {
returnJSONObject.toJSONString(map);
}
@RequestMapping(method = RequestMethod.GET, path = "/test1")
publicStringtest1(Map<String, Object> map) {
returnJSONObject.toJSONString(map);
}
@RequestMapping(method = RequestMethod.PUT, path = "/test2")
publicStringtest2(Map<String, Object> map) {
returnJSONObject.toJSONString(map);
}
@RequestMapping(method = RequestMethod.DELETE, path = "/test3")
publicStringtest3(Map<String, Object> map) {
returnJSONObject.toJSONString(map);
}

解析 multipart/form-data

@RequestMapping(method = RequestMethod.POST, path = "/uploadfile")
publicStringuploadfile(Map<String, Object> map) {
HashMap<String, String> fileInfo = newHashMap<>();
for (Stringkey : map.keySet()) {
//获取文件对象并保存Stringpath = IOUtils.saveFileUpload(key, map.get(key));
fileInfo.put(key, path);
}
returnJSONObject.toJSONString(fileInfo);
}

依赖注入 @Autowired

@ServicepublicclassTestService {
@AutowiredprivateTestDaotestDao;
publicList<Files> selectAll() {
List<Files> filesList = testDao.selectAll();
returnfilesList;
}
}

数据库连接池

hikari.properties

jdbcUrl=jdbc:mysql://localhost:3306/test?useSSL=false&useUnicode=true&characterEncoding=UTF-8
driverClassName=com.mysql.jdbc.Driver
dataSource.user=root
dataSource.password=123456
dataSource.connectionTimeout=30000
dataSource.idleTimeout=600000
dataSource.maxLifetime=1800000
dataSource.maximumPoolSize=30

Entity Class

@EntitypublicclassFiles {
@Column(name = "id")
privateStringid;
@Column(name = "name")
privateStringname;
@Column(name = "path")
privateStringpath;
@Column(name = "type")
privateStringtype;
publicStringgetId() {
returnid;
}
/*Getter、Setter*/
}

demo

@RequestMapping(method = RequestMethod.GET, path = "/dbtest")
publicStringtest5(Map<String, Object> map) {
try {
Connectionconnection = ContextConfig.poolUtils.getConnection();
PreparedStatementpreparedStatement = connection.prepareStatement("SELECT * FROM t_files");
ResultSetresultSet = preparedStatement.executeQuery();
List<Files> filesList = newResultSetMapper<Files>().mapRersultSetToObject(resultSet, Files.class);
returnJSONObject.toJSONString(filesList);
} catch (SQLExceptione) {
e.printStackTrace();
}
return"";
}

那当然是我太菜了，不是netty的问题
