I have a json field which is called template.welcome.email and I am writing a unit test that checks if that field is present in the reply from the server but I can't find an escape for the dots in the name of the field. The code of my test is :
@Test
public void testEmailTemplates() throws Exception {
mockMvc.perform(get("/emailTemplates")
.contentType(MediaType.APPLICATION_JSON)
.locale(Locale.UK)
.accept(MediaType.APPLICATION_JSON))
.andDo(print())
.andExpect(status().isOk())
.andExpect(jsonPath("$.template.welcome.email").exists())
.andExpect(redirectedUrl(null))
.andExpect(forwardedUrl(null));
}
But I get the following exception, because the dots are interpreted like paths:
java.lang.AssertionError: No value for JSON path: $.template.welcome.email, exception: invalid path

Do you know any escape character for the jsonPath?
Use brackets and quotes around your field. For example, if your field is valid.key.with.dot
Refer to it as ['valid.key.with.dot']
and in JsonPath, try
JsonPath.read(jsonString, "$.['valid.key.with.dot']")

As Ida pointed out:

Refer to it as ['valid.key.with.dot'] and in JsonPath, try
JsonPath.read(jsonString, "$.['valid.key.with.dot']")
These days (e.g. io.rest-assured.json-path:3.0.1
) the notation seems to be without brackets:
// Some Groovy OData V4 $count test
// Response looks like:
// { "@odata.count": 2, ... }
body "'@odata.count'", equalTo(2)
I found the corresponding hint in this Git issue.
