JsonLineMapper (Spring Batch 4.1.4.RELEASE API)

java.lang.Object
- org.springframework.batch.item.file.mapping.JsonLineMapper

All Implemented Interfaces:
LineMapper<java.util.Map<java.lang.String,java.lang.Object>>
```
public class JsonLineMapper
extends java.lang.Object
implements LineMapper<java.util.Map<java.lang.String,java.lang.Object>>
```
Interpret a line as a JSON object and parse it up to a Map. The line should be a standard JSON object, starting with "{" and ending with "}" and composed of name:value pairs separated by commas. Whitespace is ignored, e.g.
```
 { "foo" : "bar", "value" : 123 }
 
```
The values can also be JSON objects (which are converted to maps):
```
 { "foo": "bar", "map": { "one": 1, "two": 2}}
 
```
