Spring MVC Test安装程序在加载ApplicationContext.xml时失败

Question

Currently I'm trying to setup Spring MVC Controller testing for a school project I'm working on next to my job. Normally I program in php and frameworks like Laravel so this is pretty new for me. The problem is that I can't figure out how to solve the problem that keeps popping up on loading the ApplicationContext. Any help is appreciated.

Update:

I'm now told that test cases don't use a jndi ref in my app server. So this reference would fail on a test case, it runs fine on starting the application. Now I made a second file called servlet-test.xml (listed below) that uses a reference to the database on port 3306. I only use this file on tests not when starting up the application. But when I use this method I get Following error: Error creating bean with name 'productController': Injection of autowired dependencies failed . Any help is welcome as I'm struggling to setup MVC Controller tests for my school project. Other students I've been working with also are stuck with the same problem I am so I could help them out too.

I suspect the problem is the following, but I'm not sure how to solve this.

Error creating bean with name 'myDataSource' defined in URL 
[file:web/WEB-INF/servlet.xml]: Invocation of init method failed; 
nested exception is javax.naming.NamingException: Lookup failed for

This shows how the datasource is configured.

Answer 1

According to your stack trace when application context is initializing it still try to load wrong configuration files (servlet.xml), but should load servlet-test.xml. Please try to change your config locations with using path from root (src) folder, such as:

@ContextConfiguration({"file:src/main/web/WEB-INF/servlet-test.xml", "file:src/main/web/WEB-INF/dispatcher-servlet.xml"})

PS Also you can try to move your config for tests (servlet-test.xml) to src/test/resources and load it from classpath: "classpath:servlet-test.xml". Also you can check this thread on stackoverflow: Spring @ContextConfiguration how to put the right location for the xml for extended discussion of similar problem.

Answer 2

You get an error which says that Spring IOC container fails to create and instantiate entityManagerFactory bean. Why?

That's another thing that your error exception mention. It fails to do so because it can't instantiate the myDataSource bean. Why?

According to your error message:

 Lookup failed for 'java:app/fotoproducent'

It means that when IOC Spring container tried to create myDataSource bean, it failed to do so because it failed to set the jndiName with value of java:app/fotoproducent

Instead of using this:

<bean id="myDataSource" class="org.springframework.jndi.JndiObjectFactoryBean" scope="singleton"> 
    <property name="jndiName" value="java:app/fotoproducent" /> 
    <property name="resourceRef" value="true" /> 
</bean>

Replace it with:

<bean id="myDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="your_driver_class_name" />
    <property name="url" value="url_to_your_db" />
    <property name="username" value="user_name_to_db" />
    <property name="password" value="password_to_db" />
</bean>

My suggestion is to create a standard dataSource like mentioned on Spring docs above.

Now don't forget to replace the values for driver class name, url, user name, and password.

Here is an example from Spring docs, of how to define a data source for use of Hibernate ORM: http://docs.spring.io/spring/docs/current/spring-framework-reference/htmlsingle/#orm-hibernate
