jsonGet

Flux<JsonValue> jsonGet(K key,
                        JsonGetArgs options,
                        JsonPath... jsonPaths)

Return the value at the specified path in JSON serialized form.

When using a single JSONPath, the root of the matching values is a JSON string with a top-level array of serialized JSON value. In contrast, a legacy path returns a single value.

When using multiple JSONPath arguments, the root of the matching values is a JSON string with a top-level object, with each object value being a top-level array of serialized JSON value. In contrast, if all paths are legacy paths, each object value is a single serialized JSON value. If there are multiple paths that include both legacy path and JSONPath, the returned value conforms to the JSONPath version (an array of values).

Parameters:

key - the key holding the JSON document.

options - the JsonGetArgs to use.

jsonPaths - the JsonPaths to use to identify the values to get.

Returns:

JsonValue the value at path in JSON serialized form, or null if the path does not exist.

Since:

6.5

jsonGet

Flux<JsonValue> jsonGet(K key,
                        JsonPath... jsonPaths)

Return the value at the specified path in JSON serialized form. Uses defaults for the JsonGetArgs.

When using a single JSONPath, the root of the matching values is a JSON string with a top-level array of serialized JSON value. In contrast, a legacy path returns a single value.

When using multiple JSONPath arguments, the root of the matching values is a JSON string with a top-level object, with each object value being a top-level array of serialized JSON value. In contrast, if all paths are legacy paths, each object value is a single serialized JSON value. If there are multiple paths that include both legacy path and JSONPath, the returned value conforms to the JSONPath version (an array of values).

Parameters:

key - the key holding the JSON document.

jsonPaths - the JsonPaths to use to identify the values to get.

Returns:

JsonValue the value at path in JSON serialized form, or null if the path does not exist.

Since:

6.5

jsonMerge

Mono<String> jsonMerge(K key,
                       JsonPath jsonPath,
                       JsonValue value)

Merge a given JsonValue with the value matching JsonPath. Consequently, JSON values at matching paths are updated, deleted, or expanded with new children.

Merging is done according to the following rules per JSON value in the value argument while considering the corresponding original value if it exists:

• merging an existing object key with a null value deletes the key
• merging an existing object key with non-null value updates the value
• merging a non-existing object key adds the key and value
• merging an existing array with any merged value, replaces the entire array with the value

This command complies with RFC7396 "Json Merge Patch"

Parameters:

key - the key holding the JSON document.

jsonPath - the JsonPath pointing to the value to merge.

value - the JsonValue to merge.

Returns:

String "OK" if the set was successful, error if the operation failed.

Since:

Return the values at the specified path from multiple key arguments.

Parameters:

jsonPath - the JsonPath pointing to the value to fetch.

keys - the keys holding the JsonValues to fetch.

Returns:

List the values at path, or null if the path does not exist.

Since:

6.5

jsonMSet

Mono<String> jsonMSet(List<JsonMsetArgs<K,V>> arguments)

Set or update one or more JSON values according to the specified JsonMsetArgs

JSON.MSET is atomic, hence, all given additions or updates are either applied or not. It is not possible for clients to see that some keys were updated while others are unchanged.

A JSON value is a hierarchical structure. If you change a value in a specific path - nested values are affected.

Parameters:

arguments - the JsonMsetArgs specifying the values to change.

Returns:

"OK" if the operation was successful, error otherwise

Adds a key (with its respective value) to a JSON Object (in a RedisJSON data type key) only if it is the last child in the path, or it is the parent of a new child being added in the path. Optional arguments NX and XX modify this behavior for both new RedisJSON data type keys and the JSON Object keys in them.

jsonPath - the JsonPath pointing to the value(s) where we want to set the value.

value - the JsonValue to set.
