Release v6.2.8

This commit ensures that all non-printable characters are encoded.

Fixes gh-35034

 In most cases, you do not have to specify the `Content-Type` for each part.
 The content type is determined automatically based on the `HttpMessageConverter` chosen to serialize it or, in the case of a `Resource`, based on the file extension.

+In addition to dedicated mock web servers, historically the Spring Framework has provided

+xref:testing/testcontext-framework/bean-overriding.adoc[bean overrides] such as
+`@TestBean`, `@MockitoBean`, or `@MockitoSpyBean`, it may be desirable or necessary to

+the bean override must specify a context name that matches a name configured via the
+`name` attribute in `@ContextConfiguration`.
+
+The following test class configures the name of the second hierarchy level to be
+`"user-config"` and simultaneously specifies that the `UserService` should be wrapped in
+a Mockito spy in the context named `"user-config"`. Consequently, Spring will only
+attempt to create the spy in the `"user-config"` context and will not attempt to create

+When applying bean overrides in different levels of the context hierarchy, you may need
+to have all of the bean override instances injected into the test class in order to
+interact with them — for example, to configure stubbing for mocks. However, `@Autowired`
+will always inject a matching bean found in the lowest level of the context hierarchy.
+Thus, to inject bean override instances from specific levels in the context hierarchy,
+you need to annotate fields with appropriate bean override annotations and configure the
+name of the context level.
+
+The following test class configures the names of the hierarchy levels to be `"parent"`
+and `"child"`. It also declares two `PropertyService` fields that are configured to
+create or replace `PropertyService` beans with Mockito mocks in the respective contexts,
+named `"parent"` and `"child"`. Consequently, the mock from the `"parent"` context will
+be injected into the `propertyServiceInParent` field, and the mock from the `"child"`
+context will be injected into the `propertyServiceInChild` field.

-[[testcontext-junit4-runner]]
-== Spring JUnit 4 Runner
-
-The Spring TestContext Framework offers full integration with JUnit 4 through a custom
-runner (supported on JUnit 4.12 or higher). By annotating test classes with
-`@RunWith(SpringJUnit4ClassRunner.class)` or the shorter `@RunWith(SpringRunner.class)`
-variant, developers can implement standard JUnit 4-based unit and integration tests and
-simultaneously reap the benefits of the TestContext framework, such as support for
-loading application contexts, dependency injection of test instances, transactional test
-method execution, and so on. If you want to use the Spring TestContext Framework with an
-alternative runner (such as JUnit 4's `Parameterized` runner) or third-party runners
-(such as the `MockitoJUnitRunner`), you can, optionally, use
-xref:testing/testcontext-framework/support-classes.adoc#testcontext-junit4-rules[Spring's support for JUnit rules] instead.
-
-The following code listing shows the minimal requirements for configuring a test class to
-run with the custom Spring `Runner`:

-== Spring JUnit 4 Rules
-
-The `org.springframework.test.context.junit4.rules` package provides the following JUnit
-4 rules (supported on JUnit 4.12 or higher):
-
-* `SpringClassRule`
-* `SpringMethodRule`
-
-`SpringClassRule` is a JUnit `TestRule` that supports class-level features of the Spring
-TestContext Framework, whereas `SpringMethodRule` is a JUnit `MethodRule` that supports
-instance-level and method-level features of the Spring TestContext Framework.
-
-In contrast to the `SpringRunner`, Spring's rule-based JUnit support has the advantage of
-being independent of any `org.junit.runner.Runner` implementation and can, therefore, be
-combined with existing alternative runners (such as JUnit 4's `Parameterized`) or
-third-party runners (such as the `MockitoJUnitRunner`).

-
-* `AbstractJUnit4SpringContextTests`
-* `AbstractTransactionalJUnit4SpringContextTests`
-
-`AbstractJUnit4SpringContextTests` is an abstract base test class that integrates the
-Spring TestContext Framework with explicit `ApplicationContext` testing support in a
-JUnit 4 environment. When you extend `AbstractJUnit4SpringContextTests`, you can access a
-`protected` `applicationContext` instance variable that you can use to perform explicit
-bean lookups or to test the state of the context as a whole.
-
-`AbstractTransactionalJUnit4SpringContextTests` is an abstract transactional extension of
-`AbstractJUnit4SpringContextTests` that adds some convenience functionality for JDBC
-access. This class expects a `javax.sql.DataSource` bean and a
-`PlatformTransactionManager` bean to be defined in the `ApplicationContext`. When you
-extend `AbstractTransactionalJUnit4SpringContextTests`, you can access a `protected`
-`jdbcTemplate` instance variable that you can use to run SQL statements to query the
-database. You can use such queries to confirm database state both before and after
-running database-related application code, and Spring ensures that such queries run in
-the scope of the same transaction as the application code. When used in conjunction with
-an ORM tool, be sure to avoid xref:testing/testcontext-framework/tx.adoc#testcontext-tx-false-positives[false positives].
-As mentioned in xref:testing/support-jdbc.adoc[JDBC Testing Support],
-`AbstractTransactionalJUnit4SpringContextTests` also provides convenience methods that
-delegate to methods in `JdbcTestUtils` by using the aforementioned `jdbcTemplate`.
-Furthermore, `AbstractTransactionalJUnit4SpringContextTests` provides an
-`executeSqlScript(..)` method for running SQL scripts against the configured `DataSource`.
-
-TIP: These classes are a convenience for extension. If you do not want your test classes
-to be tied to a Spring-specific class hierarchy, you can configure your own custom test
