I would like to add caching to my Spring Boot 4 application. As a key I would like to use id (type Long) of my entity, value is my entity.
My repository extends CrudRepository.
I cache data for findOne method:
public interface SampleEntityService extends CrudRepository<SampleEntity, Long> {
#Cacheable(key = "#a0", value = "findOne")
SampleEntity findOne(Long id);
So I would like to invalidate caches for method save iterable of entities (to be consistent):
#CacheEvict(value = FIND_ONE, key = "#entities.id")
<S extends SampleEntity> Iterable<S> save(Iterable<S> entities);
but when I call this method:
sampleEntityService.save(ImmutableList.of(entity1));
I got an exception:
org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 10): Property or field 'id' cannot be found on object of type 'com.google.common.collect.SingletonImmutableList' - maybe not public?

-How can I fix this EL expression to invalidate all items in the cache which id is in the collection ?
-If this is not possible, how to make this method not supported (without writing specific implementation - I like interface magic) ?
You cannot use #CacheEvict the way you mentioned (with Iterable).
When using "key" attribute of #CacheEvict, the SpEL should point to a single id of the entity that is to be removed from specified cache(s).
It is not directly mentioned in the docs though (http://docs.spring.io/spring/docs/current/spring-framework-reference/html/cache.html#cache-annotations-evict)

I have a domain called UserAdvice which has a variable of type PriceWithPaf, which has 2 variables in it, which are again of custom-type/class-object. I have declared both the inner-objects/variables and the parent class which is a variable in the Domain as #DynamoDBDocument.
The best part is I am able to save the data exactly the way I want in DynamoDB Database but when I read the data back to object I get following error:
(I am using spring data for dynamoDB - from github & this error is shown in test case - where I use AmazonDynamoDBLocal)

After facing this issue and trying to solve it for 3 days. Finally came across this article , it worked .
My mistake was :
Initial
#DynamoDBAttribute
public String getPeriod() {
return period;
}
public void set_period(String period) {
this.period = period;
}
Changed it to :
#DynamoDBAttribute
public String getPeriod() {
return period;
}
public void setPeriod(String period) {
this.period = period;
}
It worked - the error was due to wrong getter setup - one of the getter was suppose to return custom object (PriceWithPaf) instead of returning a double.
This made the unmapping of dynamoDBDocument go wrong.
using DynamoDBDocument is easy - just put this annotation on all the class which acts as a variable to the Domain Class. and make sure your getter and setter are default/not manipulated ;)
I'm having problem with a Unit Test for a spring JPA repository.
I added another method to the repository which should return only entities for the logged in user:
#Query("select budget from Budget budget where budget.user.login = ?#{principal.username}")
List<Budget> findByUserIsCurrentUser();
Budget Resource:
/**
* GET /budgets : get all the budgets.
*
* #return the ResponseEntity with status 200 (OK) and the list of budgets in body
*/
#GetMapping("/budgets")
#Timed
public List<Budget> getAllBudgets() {
log.debug("REST request to get all Budgets");
return budgetRepository.findByUserIsCurrentUser();
}
I adjusted the test for the getAllBudgets and added the .with(user) part:
#Test
#Transactional
public void getAllBudgets() throws Exception {
budgetRepository.saveAndFlush(budget);
// Create security-aware mockMvc
restBudgetMockMvc = MockMvcBuilders
.webAppContextSetup(context)
.apply(springSecurity())
.build();
budgetRepository.saveAndFlush(budget);
// Get all the points
restBudgetMockMvc.perform(get("/api/budgets?sort=id,desc")
.with(user("user").roles("user")))
.andExpect(status().isOk())
.andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8_VALUE))
.andExpect(jsonPath("$.[*].id").value(hasItem(budget.getId().intValue())))
.andExpect(jsonPath("$.[*].name").value(hasItem(DEFAULT_NAME.toString())));
}
But now the test Fails with https://pastebin.com/8aLDTauC:

It seems that there is no value in the array, but it is working fine without the user part. The application itself is working fine, what do I need to change to get the test working with the User?
Your test initialization is wrong: budget is not attached to any user, that's why the repository method returns an empty list.
User user = userRepository.findOneByLogin("user").get();
budget.setUser(user);
budgetRepository.saveAndFlush(budget);
Using a #Query with principal makes it difficult to debug, I prefer a more explicit approach where the login is provided by the resource controller:
#GetMapping("/budgets")
public ResponseEntity<List<Budget>> getMyBudgets() {
List<Budget> budgets = budgetRepository.findByUserLogin(SecurityUtils.getCurrentUserLogin());
return ResponseEntity.ok().body(budgets);
}
and then the repository no longer needs a #Query:
public interface BudgetRepository extends JpaRepository<Budget,Long> {
List<Budget> findAll();
List<Budget> findByUserLogin(String login);
}
As a bonus, you can use same method for an administrator that would want to find the budgets of any user.
#NotNull
#JsonTypeInfo(
use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.EXTERNAL_PROPERTY,
property = "type")
#JsonSubTypes(value = {#JsonSubTypes.Type(value = SimpleGrantedAuthority.class)})
private List<GrantedAuthority> authorityList;
Above is my attribute which is a Spring Security interface for setting/authorizing users. In my test, I use the statement below to serialize to JSON as it'll be a an array or list within the JSON request body injected using camel content enricher.
String jsonObject = mapper.writeValueAsString(accountDetails);
I get this error because of that above line:

Any help will be much appreciated.
If you've found this page because you're trying to Serialize an object in Spring's JsonSerializer using the JsonGenerator.write(String/Number)Field function and see the com.fasterxml.jackson.core.JsonGenerationException: Can not write a field name, expecting a value error even though you've supplied a value:
Make sure that before you call writeField you've called JsonGenerator.writeStartObject();
Change this
#JsonSubTypes(value = {
#JsonSubTypes.Type(value = SimpleGrantedAuthority.class)
}
)
to this,
#JsonSubTypes({
#JsonSubTypes.Type(value = SimpleGrantedAuthority.class, name = "ROLE_ADMIN"),
})
Here name parameter of the JsonSubTypes should be the name you used in the JSON object to identify that sub class.
In my application I have an instance of A, when I update Ai, I want to create a copy of Ai with all previous values and insert that.
To do this work, I made a PreUpdateEventListener and in the onPreUpdate method, I want to create that clone, and then save it as a new instance, so assign Id:0 and then treat it as a new insertion.
To do that, I've:
from the SessionFactory, I opened a new Session
from that new session, using the Ai identifier, I've loaded the instance with previous state
I closed the newly created session
then I created a new instance, the clone, and then I copied into all the values treating associations so they could be treated as new ones
then I saved the new instance, the clone, in the current session
Everything seems to work, but when my code calls the flush (the caller code) I get a fantastic:

Any help is apprechiated!
Thanks in advance
Some code returns a package protected type which I am trying to mock. I was doing so using Class.forName, but Maven throws an IllegalAccessError now.
Here is a sample:
Class<?> itemSupportClasss = Class.forName("com.amazonaws.services.dynamodbv2.document.internal.IteratorSupport");
Iterator<Item> mockIterator = (Iterator<Item>) createMock(itemSupportClasss);
expect(mockIterator.hasNext()).andReturn(false);
ItemCollection<QueryOutcome> itemCollection = createMock(ItemCollection.class);
expect(((Iterable<Item>) itemCollection).iterator()).andReturn(mockIterator);
// And so on
When itemCollection.iterator() is called, I get the following error:
java.lang.IllegalAccessError: com/amazonaws/services/dynamodbv2/document/internal/IteratorSupport
at com.amazonaws.services.dynamodbv2.document.ItemCollection$$EnhancerByCGLIB$$14504e4e.iterator(<generated>)

Of course, the root issue is that Dynamo DB returns a package protected class as an iterator, but what can you do?
The real problem here is that you are trying to mock ItemCollection and have it return a real object. The only way you're going to be able to solve this problem, unfortunately, is using PowerMock:
https://code.google.com/p/powermock/wiki/Motivation
https://code.google.com/p/powermock/wiki/BypassEncapsulation
All you have to do, when using the PowerMockRunner, is put the package private class in #PrepareForTest and it should handle it for you. If this is not enough for you let me know in the comments.
