So, when i updated sdk to L version i had same problem. But after Extra folders updating in SDK Manager i didn’t find annotation.jar file. Maybe Google bug with new SDK version. So i copied annotation.jar file from old SDK folder (folder half a year ago)
Putting annotations on methods forces JPA to access properties via methods. It makes sense when internal state of your object differs from the database schema: @Entity public class Employee { private String firstName; private String lastName; @Column(name = “EMP_NAME”) // Due to legacy database schema public String getName() { return fisrtName + ” ” + … Read more
The problem is that GenericTraversableTemplate is used twice: once for mutable collections (where its type parameter should be invariant), and once for immutable collections (where covariance is invariably king). GenericTraversableTemplate’s typechecks assuming either covariance or invariance for the A type parameter. However, when we inherit it in a mutable trait, we have to pick invariance. … Read more
Close the project. In the “Welcome to Android Studio” dialog click “Configure” in the bottom right corner. Then, Settings > Build, Execution, Deployment > Compiler > Annotation Processors. Tick ‘Enable annotation processing’. If that does not work. Delete the project from “Welcome to Android Studio” dialog and open from new. Worked for me.
both may be accessed at the run-time anyway. That’s not what the javadoc says: RUNTIME: Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively. CLASS: Annotations are to be recorded in the class file by the compiler but … Read more
<mvc:annotation-driven /> means that you can define spring beans dependencies without actually having to specify a bunch of elements in XML or implement an interface or extend a base class. For example @Repository to tell spring that a class is a Dao without having to extend JpaDaoSupport or some other subclass of DaoSupport. Similarly @Controller … Read more
The Dynamic, typesafe queries in JPA 2.0 article is a very good one on this topic, actually the best one I’ve found so far online, even better than the Chapter 23 Using the Criteria API to Create Queries from the Java EE 6 tutorials (that contains some mistakes).
Somewhere in your code you must be autowiring AdminServiceImpl like this: @Autowired private AdminServiceImpl adminService; Either depend barely on interface: @Autowired private AdminService adminService; or enabled CGLIB proxies. Similar problems Autowired spring bean is not a proxy Fixing BeanNotOfRequiredTypeException on Spring proxy cast on a non-singleton bean? Getting Spring Error “Bean named ‘x’ must be … Read more
There is no standard @NonNull annotation. Creating such an annotation was the goal of JSR 305, which has been abandoned for a long time. There will not be a standard @NonNull annotation until JSR 305 is reconstituted. Oracle has no current plans to do so. (JEE annotations are outside the scope of JSR 305.) For … Read more
Besides using @Header parameter, I’d rather use RequestInterceptor to update all your request without changing your interface. Using something like: RestAdapter.Builder builder = new RestAdapter.Builder() .setRequestInterceptor(new RequestInterceptor() { @Override public void intercept(RequestFacade request) { request.addHeader(“Accept”, “application/json;versions=1”); if (isUserLoggedIn()) { request.addHeader(“Authorization”, getToken()); } } }); p/s : If you are using Retrofit2, you should use Interceptor … Read more
