程序包 org.springframework.boot.test.json

类 JacksonTester<T>

java.lang.Object

org.springframework.boot.test.json.AbstractJsonMarshalTester<T>

org.springframework.boot.test.json.JacksonTester<T>

类型参数:

T - the type under test

public class JacksonTester<T>
extends AbstractJsonMarshalTester<T>

AssertJ based JSON tester backed by Jackson. Usually instantiated via initFields(Object, ObjectMapper), for example:

 public class ExampleObjectJsonTests {

     private JacksonTester<ExampleObject> json;

     @Before
     public void setup() {
         ObjectMapper objectMapper = new ObjectMapper();
         JacksonTester.initFields(this, objectMapper);
     }

     @Test
     public void testWriteJson() throws IOException {
         ExampleObject object = //...
         assertThat(json.write(object)).isEqualToJson("expected.json");
     }

 }

构造器详细资料

JacksonTester

protected JacksonTester(com.fasterxml.jackson.databind.ObjectMapper objectMapper)

Create a new JacksonTester instance.

参数:

objectMapper - the Jackson object mapper

JacksonTester

public JacksonTester(Class<?> resourceLoadClass,
 ResolvableType type,
 com.fasterxml.jackson.databind.ObjectMapper objectMapper)

Create a new JacksonTester instance.

参数:

resourceLoadClass - the source class used to load resources

type - the type under test

objectMapper - the Jackson object mapper

JacksonTester

public JacksonTester(Class<?> resourceLoadClass,
 ResolvableType type,
 com.fasterxml.jackson.databind.ObjectMapper objectMapper,
 Class<?> view)

方法详细资料

getJsonContent

protected JsonContent<T> getJsonContent(String json)

从类复制的说明: AbstractJsonMarshalTester

Factory method used to get a JsonContent instance from a source JSON string.

覆盖:

getJsonContent 在类中 AbstractJsonMarshalTester<T>

参数:

json - the source JSON

返回:

a new JsonContent instance

readObject

protected T readObject(InputStream inputStream,
 ResolvableType type)
                throws IOException

从类复制的说明: AbstractJsonMarshalTester

Read from the specified input stream to create an object of the specified type. The default implementation delegates to AbstractJsonMarshalTester.readObject(Reader, ResolvableType).

覆盖:

readObject 在类中 AbstractJsonMarshalTester<T>

参数:

inputStream - the source input stream (never null)

type - the resulting type (never null)

返回:

the resulting object

抛出:

IOException - on read error

readObject

protected T readObject(Reader reader,
 ResolvableType type)
                throws IOException

从类复制的说明: AbstractJsonMarshalTester

Read from the specified reader to create an object of the specified type.

指定者:

readObject 在类中 AbstractJsonMarshalTester<T>

参数:

reader - the source reader (never null)

type - the resulting type (never null)

返回:

the resulting object

抛出:

IOException - on read error

writeObject

protected String writeObject(T value,
 ResolvableType type)
                      throws IOException

从类复制的说明: AbstractJsonMarshalTester

Write the specified object to a JSON string.

指定者:

writeObject 在类中 AbstractJsonMarshalTester<T>

参数:

value - the source value (never null)

type - the resulting type (never null)

返回:

the JSON string

抛出:

IOException - on write error

initFields

public static void initFields(Object testInstance,
 com.fasterxml.jackson.databind.ObjectMapper objectMapper)

Utility method to initialize JacksonTester fields. See class-level documentation for example usage.

参数:

testInstance - the test instance

objectMapper - the object mapper

另请参阅:

• initFields(Object, ObjectMapper)

initFields

public static void initFields(Object testInstance,
 ObjectFactory<com.fasterxml.jackson.databind.ObjectMapper> objectMapperFactory)

Utility method to initialize JacksonTester fields. See class-level documentation for example usage.

参数:

testInstance - the test instance

objectMapperFactory - a factory to create the object mapper

另请参阅:

• initFields(Object, ObjectMapper)

forView

public JacksonTester<T> forView(Class<?> view)

Returns a new instance of JacksonTester with the view that should be used for json serialization/deserialization.

参数:

view - the view class
