This is similar to using a Filter but can be declared within Spring MVC and combined with fine-grained @CrossOrigin configuration. According to offcial Spring Boot documentation : Enabling Cross Origin Requests for a RESTful Web Service Here's an example of how to configure CORS with annotations and filters : Enabling CORS Controller method CORS configuration So that the RESTful web service will include CORS access control headers in its response, you just have to add a annotation to the handler method: Global CORS . The value of the content attribute changes from Hello, World! The following topics describe how to do so: So that the RESTful web service will include CORS access control headers in its response, you have to add a @CrossOrigin annotation to the handler method, as the following listing (from src/main/java/com/example/restservicecors/GreetingController.java) shows: This @CrossOrigin annotation enables cross-origin resource sharing only for this specific method. Spring will combine attributes from both annotations to create a merged CORS configuration. Doing so not only avoids a collision between the two applications but also ensures that the client code is served from a different origin than the service. In Spring boot we have cors which stands for Cross-Origin Resource Sharing, it basically means that the host which is representing the UI, and the host which serves the data both are different. This service differs slightly from the one described in Building a RESTful Web Service, in that it uses Spring Framework CORS support to add the relevant CORS response headers. Perform some request processing before the request is handed over to the controller. In some cases, we need to enable CORS for requests matching to a provided/built-in filter chain but we dont want to override the whole chain logic, we just want that it enable CORS for accepting pre-flight requests and special requests from other origins.

When overriding a built-in chain on a particular area is not straight, a simpler approach is adding CORS as a default/original filter. Download the resulting ZIP file, which is an archive of a web application that is configured with your choices. While working on this, lets keep in mind following important points: We can also use this annotation at both controller and method level. @CrossOrigin Spring Boot and CORS.

You can also import the code straight into your IDE: Like most Spring Getting Started guides, you can start from scratch and complete each step or you can bypass basic setup steps that are already familiar to you. Lets for understanding take an example of angular and spring boot application which runs on the different host, so whenever we try to make calls to the backend for data from frontend we may encounter this issue in the console. 4) And now run the mainspring application to see changes and it should run fine. In fact it is an object used to intercept the HTTP requests and responses of your application. For this to work, we need to enable CORS in the Spring Boot application.

By default, all origins and GET, HEAD, and POST methods are allowed. You can find more information about Spring CORS support in this blog post. return new ResponseEntity<>("I am get method " + test, HttpStatus.OK); Lets say we have one application in angular which runs on a different host, and the backend is in spring boot which runs on a different host, so while making any request for data to the backend we may encounter this error in the console.

The implementation of the method body creates and returns a new Greeting object, with the value of the id attribute based on the next value from the counter and the value of the content based on the query parameter or the default value. Alternatively, you can build the JAR file with ./mvnw clean package and then run the JAR file, as follows: Logging output is displayed. Here is a class that uses the second way : Using the second or the third way makes sense if we want to define specific values instead of default values provided by spring security corsFilter/corsConfiguration. Let's take a closer look at each of them in detail see below; 1) Use @CrossOrigin at method level: In spring boot we can annotate our handler method with this annotation, so spring boot will handle this for us.
