- java.util.AbstractMap<K,V>
- - java.util.concurrent.ConcurrentHashMap<String,Object>
  - - org.springframework.ui.ConcurrentModel

所有已实现的接口:
Serializable, ConcurrentMap<String,Object>, Map<String,Object>, Model
直接已知子类:
BindingAwareConcurrentModel
```
public class ConcurrentModel
extends ConcurrentHashMap<String,Object>
implements Model
```
Implementation of the Model interface based on a ConcurrentHashMap for use in concurrent scenarios.
Exposed to handler methods by Spring WebFlux, typically via a declaration of the Model interface. There is typically no need to create it within user code. If necessary a handler method can return a regular java.util.Map, likely a java.util.ConcurrentMap, for a pre-determined model.

构造器概要

构造器
构造器	说明
`ConcurrentModel()`	Construct a new, empty `ConcurrentModel`.
`ConcurrentModel(Object attributeValue)`	Construct a new `ModelMap` containing the supplied attribute.
`ConcurrentModel(String attributeName, Object attributeValue)`	Construct a new `ModelMap` containing the supplied attribute under the supplied name.

方法概要

所有方法实例方法具体方法
修饰符和类型	方法	说明
`ConcurrentModel`	`addAllAttributes(Collection<?> attributeValues)`	Copy all attributes in the supplied `Collection` into this `Map`, using attribute name generation for each element.
`ConcurrentModel`	`addAllAttributes(Map<String,?> attributes)`	Copy all attributes in the supplied `Map` into this `Map`.
`ConcurrentModel`	`addAttribute(Object attributeValue)`	Add the supplied attribute to this `Map` using a `generated name`.
`ConcurrentModel`	`addAttribute(String attributeName, Object attributeValue)`	Add the supplied attribute under the supplied name.
`Map<String,Object>`	`asMap()`	Return the current set of model attributes as a Map.
`boolean`	`containsAttribute(String attributeName)`	Does this model contain an attribute of the given name?
`Object`	`getAttribute(String attributeName)`	Return the attribute value for the given name, if any.
`ConcurrentModel`	`mergeAttributes(Map<String,?> attributes)`	Copy all attributes in the supplied `Map` into this `Map`, with existing objects of the same name taking precedence (i.e. not getting replaced).
`Object`	`put(String key, Object value)`
`void`	`putAll(Map<? extends String,?> map)`

  - ConcurrentModel
```
public ConcurrentModel()
```
    Construct a new, empty ConcurrentModel.
  - ConcurrentModel
```
public ConcurrentModel(String attributeName,
                       Object attributeValue)
```
    Construct a new ModelMap containing the supplied attribute under the supplied name.
    另请参阅:
    addAttribute(String, Object)
  - ConcurrentModel
```
public ConcurrentModel(Object attributeValue)
```
    Construct a new ModelMap containing the supplied attribute. Uses attribute name generation to generate the key for the supplied model object.

    addAttribute(Object)

  - put
```
public Object put(String key,
                  Object value)
```
    指定者:
    put 在接口中 Map<String,Object>
    覆盖:
    put 在类中 ConcurrentHashMap<String,Object>
  - putAll
```
public void putAll(Map<? extends String,?> map)
```
    指定者:
    putAll 在接口中 Map<String,Object>
    覆盖:
    putAll 在类中 ConcurrentHashMap<String,Object>
  - addAttribute
```
public ConcurrentModel addAttribute(String attributeName,

                                    Object attributeValue)
```
    Add the supplied attribute under the supplied name.
    指定者:
    addAttribute 在接口中 Model
    参数:
    attributeName - the name of the model attribute (never null)
    attributeValue - the model attribute value (ignored if null, just removing an existing entry if any)
  - addAttribute
```
public ConcurrentModel addAttribute(Object attributeValue)
```
    Add the supplied attribute to this Map using a generated name.
    Note: Empty Collections are not added to the model when using this method because we cannot correctly determine the true convention name. View code should check for null rather than for empty collections as is already done by JSTL tags.
    指定者:
    addAttribute 在接口中 Model
    参数:
    attributeValue - the model attribute value (never null)
  - addAllAttributes
```
public ConcurrentModel addAllAttributes(@Nullable
                                        Collection<?> attributeValues)
```
    Copy all attributes in the supplied Collection into this Map, using attribute name generation for each element.
    指定者:
    addAllAttributes 在接口中 Model
    另请参阅:
    addAttribute(Object)
  - addAllAttributes
```
public ConcurrentModel addAllAttributes(@Nullable
                                        Map<String,?> attributes)
```
    Copy all attributes in the supplied Map into this Map.

  - mergeAttributes
```
public ConcurrentModel mergeAttributes(@Nullable
                                       Map<String,?> attributes)
```
    Copy all attributes in the supplied Map into this Map, with existing objects of the same name taking precedence (i.e. not getting replaced).
    指定者:
    mergeAttributes 在接口中 Model
  - containsAttribute
```
public boolean containsAttribute(String attributeName)
```
    Does this model contain an attribute of the given name?
    指定者:
    containsAttribute 在接口中 Model
    参数:
    attributeName - the name of the model attribute (never null)
    返回:
    whether this model contains a corresponding attribute
  - getAttribute
```
@Nullable
public Object getAttribute(String attributeName)
```
    从接口复制的说明: Model
    Return the attribute value for the given name, if any.
    指定者:
    getAttribute 在接口中 Model
    参数:
    attributeName - the name of the model attribute (never null)
    返回:
    the corresponding attribute value, or null if none
