MyEclipse无法实现AutoBoxing/AutoUnBoxing问题

Question

程序代码如下：

import java.util.HashMap;
import java.util.Map;

public class WordConstants {
private static Map typeNameValue=new HashMap();
static{
[color=red]typeNameValue.put("a", 1);
typeNameValue.put("an", 2);
typeNameValue.put("i", 3);
typeNameValue.put("j", 4);
typeNameValue.put("l", 5);
typeNameValue.put("Ng", 6);
typeNameValue.put("n", 7);
typeNameValue.put("nr", 8);
typeNameValue.put("ns", 9);
typeNameValue.put("nt", 10);
typeNameValue.put("nz", 11);
typeNameValue.put("v", 12);
typeNameValue.put("vm", 13);[/color] }
public static int getTypeByName(String _sName){
[color=blue]return typeNameValue.get(_sName);[/color] }
}

红色部分提示“The method put(String,Integer) in the type Map(String,Integer) is not applicable for the arguments(String,int)”
蓝色部分提示“Tye mismatch: cannot convert from Integer to int”
上段代码在命令行环境下运行却可顺利编译

在同样的MyEclipse环境下，不同的工程中，另一段相似代码却没有提示出错信息。相似代码如下：

package com.pureinfo.segword;

import java.util.HashMap;
import java.util.Map;

public class WordConstants {

迫切希望各位能帮忙解答，谢谢~

Answer 1

工程右键->properties->Java Compiler
看右边compiler compliance level 是不是4.0
是的话钩上上边的复选框,改成5.0或6.0
