具体报错：2019-03-19 12:01:35,097 - request - DEBUG - json_data: {\'timestamp\': 1552968086846, \'status\': 400, \'error\': \'Bad Request\', \'exception\': \'org.springframework.http.converter.HttpMessageNotReadableException\', \'message\': "JSON parse error: Unrecognized token \'halfSelectedKeys\': was expecting (\'true\', \'false\' or \'null\'); nested exception is com.fasterxml.jackson.core.JsonParseException: Unrecognized token \'halfSelectedKeys\': was expecting (\'true\', \'false\' or \'null\')\n at [Source: java.io.PushbackInputStream@6616c7bd; line: 1, column: 18]", \'path\': \'/v1/oms/role\'}
