is(nullValue()) and doesNotExist() for jayway.jsonpath

There are Account and AccountResource in my application. For testing, I add @JsonIgnore before my getPassword() method so that it won't return password for my test.

I use jayway.jsonpath to validate those returned value;

If the version of jayway.jsonpath is 0.9 and older, is(nullValue()) can be used:

mockMvc.perform(get("/rest/accounts/1"))
        .andDo(print())
        .andExpect(jsonPath("$.password", is(nullValue())))

But for any newer version, the is(nullValue()) will throw exception:

java.lang.AssertionError: No value for JSON path: $.password, exception: No results for path: $['password']

To solve this problem for any version that is later than 0.9, we use the doesNotExist() instead, i.e:

mockMvc.perform(get("/rest/accounts/1"))
       .andDo(print())
       .andExpect(jsonPath("$.password").doesNotExist())
