运行 spring 批处理作业时无法反序列化执行上下文异常

Question

I am executing some spring batch job and getting the following exception:

Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDate` (no Creators, like default construct, exist): cannot deserialize from Object value (no delegate- or property-based Creator)
 at [Source: (ByteArrayInputStream); line: 1, column: 447] (through reference chain: java.util.HashMap["TEST_FF_EXCEPTION"]-com.example.model.TestFFContext["cobDate"])

Assuming that it is some kind of date serialization issue, I have tried the following:

public class LocalDateDeserializer extends StdDeserializer<LocalDate> {

    public LocalDateDeserializer() {
        super(LocalDate.class);
    }

    @Override
    public LocalDate deserialize(final JsonParser jsonParser, final DeserializationContext deserializationContext)
            throws IOException {
        return LocalDate.parse(jsonParser.getText());
    }
}
    

public class LocalDateSerializer extends StdSerializer<LocalDate> {

    static final DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd");

    public LocalDateSerializer() {
        super(LocalDate.class);
    }

    @Override
    public void serialize(final LocalDate localDate, final JsonGenerator jsonGenerator,
                          final SerializerProvider serializerProvider) throws IOException {
        final String formattedDateTime = localDate.format(FORMATTER);
        jsonGenerator.writeString(formattedDateTime);
    }
}


public final class TestFFContext {

    private String name;

    @JsonDeserialize(using = LocalDateDeserializer.class)
    @JsonSerialize(using = LocalDateSerializer.class)
    private LocalDate cobDate;
    
    //no args constructor
    //all args constructor
    
}

But getting the following:

   Caused by: com.fasterxml.jackson.databind.JsonMappingException: Text '{' could not be parsed at index 0 (through reference chain: java.util.HashMap["TEST_FF_CONTEXT"]->com.example.model.TestFFContext["cobDate"])

Anyone can give me any pointers what I am missing here?

it is tripping up in ExecutionContextRowMapper() when deserialising inputstream. This is only happening in the case of my bdd test. When running the spring boot app normally, I didnt need any custom serialization classes.

Sample json:

{
  "name": "TEST",
  "cobDate": "2020-07-28",
}

I create spring batch job parameter with cobDate from string and run job:

`execution = jobLauncher.run(job, parameters);`

After updating deserializer to use getValueAsString()

Answer 1

Use parser.getValueAsString() to get the json value for date and use formatter when parse the date string. And make sure you are importing right Deserializer on the field. I added a sample, you can use it

public class LocalDateDeserializer extends StdDeserializer<LocalDate> {

    private static final long serialVersionUID = 1608358311371702012L;

    private static final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");

    public LocalDateDeserializer() {
        this(null);
    }

    protected LocalDateDeserializer(Class<LocalDate> type) {
        super(type);
    }

    @Override
    public LocalDate deserialize(JsonParser parser, DeserializationContext context)
            throws IOException, JsonProcessingException {
        return LocalDate.parse(parser.getValueAsString(), formatter);
    }

}

Answer 2

I solved this problem by configuring a custom JobRepository that could handle JSR-310: First add com.fasterxml.jackson.datatype:jackson-datatype-jsr310 in your classpath if you don't have it already Then, my main config class for Spring batch extends DefaultBatchConfigurer from which I can override createJobRepository . I pass it an ObjectMapper configured to handle JSR-310:

@Override
protected JobRepository createJobRepository() throws Exception {
    JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
    factory.setDataSource(dataSource);
    factory.setTransactionManager(getTransactionManager());
    Jackson2ExecutionContextStringSerializer serializer = new Jackson2ExecutionContextStringSerializer();
    serializer.setObjectMapper(objectMapper());
    factory.setSerializer(serializer);
    factory.afterPropertiesSet();
    return factory.getObject();
}

@Bean
public ObjectMapper objectMapper() {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.registerModule(new JavaTimeModule());
    return objectMapper;
}
