Spring.Core.TypeMismatchException：无法转换Dictionary类型的属性值-Java 学习之路

我正在努力解决问题，非常感谢一些帮助 .

public interface ISolver<T>
{
        void Solve();
}

public class Solver : ISolve<IEntity>
{
  void Solve()
{
...code that solves the given problem
}
}

 public class Client : IClient<IEntity>
{

        public Dictionary<string, ISolver<IEntity>> Solvers { get; set; }
}

All are part of namespace solution.

在Spring.Net配置中：

<object id="Client" type="solution.Client, solution">
<property name="Solvers">
      <dictionary key-type="string" value-type="solution.Solver, solution">
        <entry  key="SolverMp" value-ref="SolverMp"></entry>
      </dictionary>
    </property>
</object>

<object id="SolverMp" type="solution.Solver, solution">
</object>

我得到了例外：

Spring.Core.TypeMismatchException：无法转换类型的属性值[System.Collections.Generic.Dictionary2 [[System.String，mscorlib，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089]，[solution.Solver] ，solution，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null]]]到必需的类型[System.Collections.Generic.Dictionary2 [[System.String，mscorlib，Version = 4.0.0.0，Culture = neutral， PublicKeyToken = b77a5c561934e089]，[solution.ISolver`1 [[solution.IEntity，solution，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null]]，solution，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null ]]]属性'Solvers' .

<objects xmlns="http://www.springframework.net">
  <object id="Client" type="solution.Client, solution">
    <property name="Solvers">
      <dictionary key-type="string" value-type="solution.ISolver&lt;solution.IEntity&gt;, solution">
        <entry key="SolverMp" value-ref="SolverMp"></entry>
      </dictionary>
    </property>
  </object>
</objects>

至少有一个问题是您的配置中的此条目：
```
value-type="solution.Solver
```
Solvers字典的值类型是
```
ISolver<IEntity>>
```
这就是异常所抱怨的 .
