Here I am Using LocalDate class of java 1.8.In my bean I took return type as LocalDate. And I am sending date formate as 07/01/2017 . when I am trying to save that I am getting follwing exception.

org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver] (default task-33) Failed to read HTTP message: org.springframework.http.converter.HttpMessageNotReadableException: Could not read document: Can not instantiate value of type [simple type, class java.time.LocalDate] from String value ('07/01/2017'); no single-String constructor/factory method

Add com.fasterxml.jackson.datatype-jsr310 dependency

Then configure Jackson2ObjectMapper with

 @Bean(name = "OBJECT_MAPPER_BEAN")
    public ObjectMapper jsonObjectMapper() {
        return Jackson2ObjectMapperBuilder.json()
                .serializationInclusion(JsonInclude.Include.NON_NULL) // Don’t include null values
                .featuresToDisable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS) //ISODate
                .modules(new JSR310Module())
                .build();
    }
