Examples with BeanSerializerFactory com.fasterxml.jackson.databind.ser.BeanSerializerFactory used on opensource projects

Example 1 with BeanSerializerFactory

use of com.fasterxml.jackson.databind.ser.BeanSerializerFactory in project jackson-databind by FasterXML.

the class TestSerializerProvider method testFindExplicit.

public void testFindExplicit() throws JsonMappingException {
    ObjectMapper mapper = new ObjectMapper();
    SerializationConfig config = mapper.getSerializationConfig();
    SerializerFactory f = new BeanSerializerFactory(null);
    DefaultSerializerProvider prov = new DefaultSerializerProvider.Impl().createInstance(config, f);
    // Should have working default key and null key serializers
    assertNotNull(prov.findKeySerializer(mapper.constructType(String.class), null));
    assertNotNull(prov.getDefaultNullKeySerializer());
    assertNotNull(prov.getDefaultNullValueSerializer());
    // as well as 'unknown type' one (throws exception)
    assertNotNull(prov.getUnknownTypeSerializer(getClass()));
    assertTrue(prov.createInstance(config, f).hasSerializerFor(String.class, null));
    // call twice to verify it'll be cached (second code path)
    assertTrue(prov.createInstance(config, f).hasSerializerFor(String.class, null));
    assertTrue(prov.createInstance(config, f).hasSerializerFor(MyBean.class, null));
    assertTrue(prov.createInstance(config, f).hasSerializerFor(MyBean.class, null));
    // And then some negative testing
    AtomicReference<Throwable> cause = new AtomicReference<Throwable>();
    assertFalse(prov.createInstance(config, f).hasSerializerFor(NoPropsBean.class, cause));
    Throwable t = cause.get();
    // no actual exception: just fails since there are no properties
    assertNull(t);
