A Simple Spring 4 and MyBatis Transaction Example

According to wikipedia, database transaction should provide an “all-or-nothing” proposition, stating that each work-unit performed in a database must either complete in its entirety or have no effect whatsoever. Further, the system must isolate each transaction from other transactions, results must conform to existing constraints in the database, and transactions that complete successfully must get written to durable storage.

So on this example, im trying to create a simple MyBatis database transaction, managed by Spring Framework. Okay, so this is my pom file, as you can see, im using Spring version 4.1.2.

This is my database structure,

CREATE TABLE `testing` (
  `Id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(30) NOT NULL DEFAULT '',
  `address` varchar(255) NOT NULL DEFAULT '',
  PRIMARY KEY (`Id`),
  UNIQUE KEY `ix` (`name`)
) 

Im mapping my “testing” table into an xml and java file,

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.edw.springmybatis.mapper.TestingMapper" >
  
    <select id="insert" parameterType="com.edw.springmybatis.bean.Testing" >
        insert into testing (name, address)
        values ( #{name,jdbcType=VARCHAR}, #{address,jdbcType=VARCHAR} )
    </select> 
  
</mapper>
package com.edw.springmybatis.bean;

import java.io.Serializable;

public class Testing implements Serializable  {

    private Integer id;
    private String name;
    private String address;

	public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
	
    // other setter and getter 

    public Testing() {
    }

    public Testing(String name, String address) {
        this.name = name;
        this.address = address;
    }
}

This is my configuration.xml file for handling all mybatis’ configuration file,

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration

"http://mybatis.org/dtd/mybatis-3-config.dtd">

</configuration>

My log4j file,

log4j.appender.stdout.layout.ConversionPattern=%d [%c{1}] %-5p %c:%L - %m%n

Okay, now is for my java class. First is MyBatis mapper file,

package com.edw.springmybatis.mapper;

import com.edw.springmybatis.bean.Testing;

public interface TestingMapper {
    public void insert(Testing testing);    
}

Next is my Service class,

package com.edw.springmybatis.service;

import com.edw.springmybatis.bean.Testing;
import com.edw.springmybatis.mapper.TestingMapper;
import java.util.Random;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public class TestingService {

    @Autowired
    private TestingMapper testingMapper;

    public void insert() throws Exception {
        testingMapper.insert(new Testing("" + new Random().nextInt(), "" + new Random().nextInt()));
        testingMapper.insert(new Testing()); // this will throw an exception
    }
}

And finally, my controller file

package com.edw.springmybatis.controller;

import com.edw.springmybatis.service.TestingService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class IndexController {

    @Autowired
    private TestingService testingService;
    
    private final Logger logger = Logger.getLogger(this.getClass());
    
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public @ResponseBody Integer index() {
        try {
            testingService.insert();
			return 1;
        } catch (Exception e) {
            logger.error(e);
        }
        return 0;
    }    
}

This is what happen when im accessing my application directly,
mybatisspring1

And this what is written on my netbeans console,
mybatisspring2

As you can see, my previous insert is rolledback so there is no new record on my “testing” table.
mybatisspring3

And this is my netbeans project structure,
mybatisspring4

You can find the sourcecode needed on my Github page.

java.sql.SQLException: Numeric Overflow When Connecting to Oracle using MyBatis

Im using mybatis framework, and it was working very nice untuil today ive found a very weird error. A very weird error, because im only doing select queries and not insert anything.

This is the complete stacktrace,

Cause: java.sql.SQLException: Numeric Overflow

	at sun.reflect.GeneratedMethodAccessor198.invoke(Unknown Source)
	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)

This is my java bean,

public class TblInvalid implements Serializable {
    private short id;

    private String attribute7;

    // other setter and getter
}

My Oracle DDL looks like this,

CREATE TABLE TBL_INVALID
    (
        ID NUMBER,
        ATTRIBUTE7 VARCHAR2(255)
 )

The workaround is actually so simple, changing from Short into BigDecimal makes the problem goes away.

public class TblInvalid implements Serializable {
    private BigDecimal id;

    private String attribute7;

    // other setter and getter
}

[Weird Javascript Error] Leading Zero on Integer Variable Become Octal on Old Browser

Ive met a very weird error, that somehow never occurs to me on my browser. I found this error only happen on old mozilla browsers, and only happen on javascript’s parseInt method. Here is a simple example,

alert(parseInt("09")-1);

When im running it on my browser (Mozilla version 34), this is what happen,
mozillanew

But when running on old browsers (Mozilla version 3.6), this is what happen,
mozillaold

I finally found out that that on old browsers, leading zeros are treated as octal values instead of plain integers. So this is my workaround,

alert(parseInt("09".replace(/^[0]+/g,""))-1);

I removed the leading zero before parsing it into int.

Hope it can help others :)

Accessing JBoss Administration Console (Port 9990) From Network

Today, i have a very weird condition, im installing Jboss EAP 6.1 but i cannot access its administration console from outside ip. Somehow, everytime i run netstat -aon command, i can see that port 9990 binded only with 127.0.0.1.

The workaround is actually very simple, i only add -bmanagement on JBoss start command,

./standalone.sh -bmanagement=0.0.0.0

And now port 9990 is accessible by other network.

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

Kemudian register konfigurasi spring di web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml, /WEB-INF/applicationSecurity.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    
    <!-- Spring Security -->
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy
        </filter-class>
    </filter>
 
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>

Dan 3 xml milik Spring, ApplicationContext.xml, dispatcher-servlet.xml dan applicationSecurity.xml

            </user-service>
        </authentication-provider>
    </authentication-manager>
    
    
</beans:beans>

Lalu gw bikin satu java class sebagai controller,

package com.edw.springsecurityexample.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class IndexController {
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String index() {
        return "index";
    }
    
    @RequestMapping(value = "/admin/index", method = RequestMethod.GET)
    public String adminIndex() {
        return "adminIndex";
    }
}

Kemudian satu jsp sederhana sebagai halaman login,

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>Hello Spring MVC!</h1>
        <h2>Tolong Login Dulu </h2>
        
        <c:if test="${not empty param.error}">
                <div style="color: red;">
                    Username atau Password Salah
                </div>
        </c:if>
        
        <form action="j_spring_security_check" method="POST">
            <table>
                <tr>
                    <td>
                        username
                    </td>
                    <td>
                        <input name="j_username" type="text" />
                    </td>
                </tr>
                <tr>
                    <td>
                        password
                    </td>
                    <td>
                        <input name="j_password" type="password" />
                    </td>
                </tr>
                <tr>
                    <td colspan="2">
                        <input name="submit" type="submit" />
                    </td>
                </tr>
            </table>
        </form>
    </body>
</html>

Dan halaman admin sederhana, yang hanya bisa diakses apabila sudah login yang isinya link logout.

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head><a href="http://edwin.baculsoft.com/wp-content/uploads/2014/11/springsecurity-login-gagal.png"><img src="http://edwin.baculsoft.com/wp-content/uploads/2014/11/springsecurity-login-gagal.png" alt="springsecurity login gagal" width="458" height="287" class="aligncenter size-full wp-image-1535" /></a>
    <body>
        <h1>Selamat, anda sudah login -- admin page</h1>
        <br />
        <a href="${pageContext.request.contextPath}/logout">logout</a>
    </body>
</html>

Berikut adalah tampilan struktur netbeans project
springsecurity project structure

Tampilan halaman login, dan tampilan jika login gagal,
springsecurity login

springsecurity login gagal

Jika login dengan username edw dan password 123456, maka akan tampil halaman seperti berikut,
springsecurity login sukses

Source lengkapnya, bisa diakses di github saya, di url ini.
