所有已实现的接口:
Ordered, TestExecutionListener
```
public class ServletTestExecutionListener
extends AbstractTestExecutionListener
```
TestExecutionListener which provides mock Servlet API support to WebApplicationContexts loaded by the Spring TestContext Framework.
Specifically, ServletTestExecutionListener sets up thread-local state via Spring Web's RequestContextHolder during test instance preparation and before each test method and creates a MockHttpServletRequest, MockHttpServletResponse, and ServletWebRequest based on the MockServletContext present in the WebApplicationContext. This listener also ensures that the MockHttpServletResponse and ServletWebRequest can be injected into the test instance, and once the test is complete this listener cleans up thread-local state.
Note that ServletTestExecutionListener is enabled by default but generally takes no action if the test class is not annotated with @WebAppConfiguration. See the javadocs for individual methods in this class for details.

修饰符和类型	方法	说明
`void`	`afterTestMethod(TestContext testContext)`	If the `RESET_REQUEST_CONTEXT_HOLDER_ATTRIBUTE` in the supplied `TestContext` has a value of `Boolean.TRUE`, this method will (1) clean up thread-local state after each test method by resetting Spring Web's `RequestContextHolder` and (2) ensure that new mocks are injected into the test instance for subsequent tests by setting the `DependencyInjectionTestExecutionListener.REINJECT_DEPENDENCIES_ATTRIBUTE` in the test context to `true`.
`void`	`beforeTestMethod(TestContext testContext)`	Sets up thread-local state before each test method via Spring Web's `RequestContextHolder`, but only if the test class is annotated with `@WebAppConfiguration`.
`int`	`getOrder()`	Returns `1000`.
`void`	`prepareTestInstance(TestContext testContext)`	Sets up thread-local state during the test instance preparation callback phase via Spring Web's `RequestContextHolder`, but only if the test class is annotated with `@WebAppConfiguration`.
