It's reading the mybatis-config.xml file, inside that i put this line
<mapper resource="com.work.dao.VillageMapper.xml" />
It's not reading, what to do?
I put the mybatis-config.xml file inside the project->src->resources->mybatis-config.xml and VillageMapper.xml file inside the dao package.
Project
-src
-com.work.controllers
-VillageController.java
-com.work.dao
-VillageMapper.java
-VillageMapper.xml
-com.work.entity
-Village.java
-com.work.util
-MyBatisUtil.java
-resources
-mybatis-config.xml
I have not used Maven for this. What should I change or correct?


In your mybatis-config.xml, you need to change your <mapper resource="com.work.dao.VillageMapper.xml" /> to <mapper resource="com/work/dao/VillageMapper.xml" />
You can refer here for simple example on spring mybatis implementation and you can also look here for more details on different types of configurations.

You need to add a modelAttribute with a proper name to your form, otherwise the form backing bean name will default to 'command' hence you get your error

Why Tiles 3.0.5 does not work on Spring web 4.1.5

I configured my Spring based application (4.1.5) to use Tiles 3.0.5.
In tiles.xml file I put a file that does not exist "ewfsdfsdf.jsp" to see if the configuration works, then I navigated to hello.htm but it shows hello.jsp rather than showing any error about not finding ewfsdfsdf.jsp file.

HelloController
package springapp.web;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.web.servlet.ModelAndView;

System.err.println("Constructor of HelloController");
}
#Override
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
logger.info("Returning hello view");
return new ModelAndView("hello");
}
}

I could solve the problem by following this tutorial and adding following line to springapp-servlet.xml and two new jars
jars
jsf-api.jar
jstl.jar
new viewResolver added
<bean id="viewResolver" class="org.springframework.web.servlet.view.tiles3.TilesViewResolver"/>

Tried everything - except what you guys might add. Again, everything seemed to be working and wired correctly. Had the Login render the login page Post the user / password in a form made a return trip tom to the DB and rendered the Home page. Once I plugged in Tiles, I can't the first page to render.

Is it tiles.xml or tile.xml ?
In tiles.xml are the Login and Home definitions supposed to extend the template definition?

autowire failing

I'm doing a spring-mvc-jpa project and my autowiring is failing on my service bean because "no matching bean was found" Below is my bean that is not found:
package com.dave.movie.repository;

import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.stereotype.Service;
import com.dave.movie.entity.*;
public interface FilmRepository extends JpaRepository<Film, Long> {
}
Service class that cannot find the bean:

The reason is because you are using Spring-Data repositories, but have not declared the tag that causes Spring data to generate the repository proxy classes and beans corresponding to the classes. This is done with the following custom tag:
<jpa:repositories base-package="com.dave.movie.repository"
entity-manager-factory-ref="entityManagerFactory"
transaction-manager-ref="transactionManager">
</jpa:repositories>

Seeing InternalResourceView in the stack trace when I am actually using UrlBasedViewResolver puzzles me even more.
The WEB-INF/views is actually prefixed some 50 odd times before throwing the error I have pasted a smaller representation of it to avoid verbosity.
Not sure what causing this effect.

Got it to work with some help from the spring forum guys, I made the following changes:
Removed the annotation-driven ad mvc:annotation-driven tags from the servlet-context and controllers XML respectively.

<!-- Scans within the base package of the application for #Components to
configure as beans -->
<context:component-scan base-package="chomu" />
<mvc:resources mapping="/resources/**" location="/resources/" />
<bean id="validator"
class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
</beans>
but the root cause was a fault in the servlet mapping, so changed the Dispatechr Servlet mapping to following in web.xml
<!-- Processes application requests -->
<servlet>
<servlet-name>appServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/app/servlet-context.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>appServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Changed /* to / which was causing the recursive addition of view since it could not find the correct one.
