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 viainitFields(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"); } }

方法详细资料
readObject
protected T readObject(InputStream inputStream, org.springframework.core.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 toAbstractJsonMarshalTester.readObject(Reader, ResolvableType)
.- 覆盖:
readObject
在类中AbstractJsonMarshalTester<T>
- 参数:
inputStream
- the source input stream (nevernull
)type
- the resulting type (nevernull
)- 返回:
- the resulting object
- 抛出:
IOException
- on read error
readObject
protected T readObject(Reader reader, org.springframework.core.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

IOException
- on read error
writeObject
protected String writeObject(T value, org.springframework.core.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 (nevernull
)type
