I have a problem with spring 4.2.5 and java8.
Trying to write simple rest:
#RequestMapping(value = "raw2", method = RequestMethod.GET)
ResponseEntity<String> getTest(#RequestParam Optional<String> p) {
return new ResponseEntity<>(HttpStatus.OK);
}
But keep getting errors:

Ensure you have added the <mvc:annotation-driven> tag in XML. This will make sure that convertors are available

I have been spending lot of times to investigate this issue, still i could't solve it. Pls help!
I encountered this error when I tried to use a type rather than input as an input, which isn't allowed. This is slightly different from the original question, but you'll see the same error:
So this was NOT working:
scalar Upload
type Mutation {
uploadFile(input: CreateFileUploadInput): Boolean
}
type CreateFileUploadInput {
files: Upload
id: String
}
This fixed it:
input CreateFileUploadInput {
files: Upload
id: String
}
(Just changed it from type to input)
I was having the same problem over here and was able to solve it (be it not in a very nice way) after reading something mentioned on https://github.com/graphql-java-kickstart/graphql-java-tools/issues/77.
It states that by using the type explicitly in the root of a query/mutation, it will also be available on a nested level. In your case this would mean adding an additional method e.g. typLoaderDummy, as shown in the sample below (which will not actually be used) to your definition. Keep in mind that you will need to provide an implementation for this "dummy" method on your Java implementation.
scalar Upload
type Mutation {
uploadFile(input: CreateFileUploadInput): Boolean
typeLoaderDummy(upload: Upload): Boolean
}
For me this workaround solved the problem.
For the first time i am using Optional in Rest Web Service to make a Path Parameter as optional.
#RequestMapping(value = {"/hosts","/hosts/{name}"}, method = RequestMethod.GET, produces = "application/json")
public ResponseEntity<Object> getHosts(#PathVariable Optional<String> name) {
if(name.isPresent()) {
return service.getHosts(name.get());
} else {
return service.getHosts(null);
}
}
When i use the API without the parameter, it works fine.
But when i give the parameter, it throws the following exception:
org.springframework.beans.ConversionNotSupportedException: Failed to convert value of type 'java.lang.String' to required type 'java.util.Optional'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [java.util.Optional]: no matching editors or conversion strategy found

I have spent quite a time debugging this but could't get past this error. Any help is appreciated.
Thanks,
Just add "mvc:annotation-driven/> to your xml file to make it work.
My Java has this
#Value("#{${validators}}")
private Map<String,String> validators;
property file has this
validators={AlphabetValidator:'AlphabetValidator',NumberValidator:'NumberValidator'AlphaNumericValidator:'AlphaNumericValidator',DateValidator:'DateValidator', FixedLengthValidator:'FixedLengthValidator',MinimumLengthValidator:'MinimumLengthValidator',MaximumLengthValidator:'MaximumLengthValidator',CustomValidator:'CustomValidator' MandatoryFieldValidator: 'MandatoryFieldValidator',TimeValidator:'TimeValidator'}
when I run the app.. I am getting this error
Exception in thread "main"
org.springframework.beans.factory.UnsatisfiedDependencyException:
Error creating bean with name 'validatorProperties': Unsatisfied
dependency expressed through field 'validators'; nested exception is
org.springframework.beans.factory.BeanExpressionException: Expression
parsing failed; nested exception is
org.springframework.expression.spel.SpelParseException: EL1041E:(pos
1): After parsing a valid expression, there is still more data in the
expression: 'lcurly({)'
Check out for comma ',' in property file.
Properties file:
validators={AlphabetValidator:'AlphabetValidator',NumberValidator:'NumberValidator',AlphaNumericValidator:'AlphaNumericValidator',DateValidator:'DateValidator',FixedLengthValidator:'FixedLengthValidator',MinimumLengthValidator:'MinimumLengthValidator',MaximumLengthValidator:'MaximumLengthValidator',CustomValidator:'CustomValidator',MandatoryFieldValidator:'MandatoryFieldValidator',TimeValidator:'TimeValidator'}
Java code:
#Value("#{${validators}}")
private Map<String,String> validators;
You have missed to specify some commas inside your properties. Try with following:
validators={AlphabetValidator:'AlphabetValidator',NumberValidator:'NumberValidator',AlphaNumericValidator:'AlphaNumericValidator',DateValidator:'DateValidator',FixedLengthValidator:'FixedLengthValidator',MinimumLengthValidator:'MinimumLengthValidator',MaximumLengthValidator:'MaximumLengthValidator',CustomValidator:'CustomValidator',MandatoryFieldValidator:'MandatoryFieldValidator',TimeValidator:'TimeValidator'}

Action:
Update your application's configuration
If I use the property server.port in my application.yml it works, no problem.
What am I doing wrong? Thanks for any help.
The issue is caused by the spring boot run configuration: In the run configuration, just disable "Fast startup" and the problem will go away. This option causes -noverify to be added as a VM argument, but, unfortunately, with no spaces.
I am using spring batch version 3.0.2.RELEASE and spring framework version 3.2.12.RELEASE. And I am trying to inject a job scoped bean to another job scoped bean.
My configuration looks like this
<bean id="beanA" class="com.trial.BeanA" scope="job" >
<property name="beanB" ref="beanB" />
</bean>
<bean id="beanB" class="com.trial.BeanB" scope="job"/>
It throws an exception with details:

Even I try to inject a "job" scoped bean to a "step" scoped bean, it fails and throws a similar exception.
How can I solve the issue?
You are using java proxying which requires interfaces, yet your BeanB doesn't implement an interface that BeanA is coded against. You need to either switch to dynamic subclassing or have BeanB implement an interface and have BeanA expect that interface.
