java web工程 添加WebLogic支持

• web.xml 由于在weblogic中通过JS异步请求直接读取XML文件，发现在IE中无法通过request.responseXML获取，因为它不认为是XML，主要是因为没有设置contentType="text/xml"，因此需要在web.xml中添加MIME映射。

• weblogic.xml（与web.xml同级） 由于jar包与WebLogic自带的冲突，需设置项目jar优先。

• ClassesFind.java 在WebLogic中普通的classloader无法获取class改用spring 2.5提供的方式查找

ClassesFind.java

package com.runjf.utils;

import java.util.Collections;
import java.util.HashSet;
import java.util.Set;

import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider;
import org.springframework.core.type.filter.AssignableTypeFilter;
import org.springframework.util.ClassUtils;

/**

public class ClassesFind {
	
	/**
	 * 加载class，采用Spring 2.5提供的{@link ClassPathScanningCandidateComponentProvider}来获取
	 * 
	 * @param basePackage 包路径 默认根路径开始查找
	 * @param include 包含的类型
	 * @return 不存在返回空的set
	 */
	public Set<Class<?>> findByPackage(String basePackage, Class<?>... include) {

		if (include != null && include.length > 0) {
			ClassPathScanningCandidateComponentProvider cpsccp = new ClassPathScanningCandidateComponentProvider(false);
			// 指定包含的类型
			for (Class<?> cls : include) {
				cpsccp.addIncludeFilter(new AssignableTypeFilter(cls));
			}
			// 查找包并制定包路径
			Set<BeanDefinition> confs = cpsccp.findCandidateComponents(basePackage == null || basePackage.trim().isEmpty() ? "/" : basePackage);
			
			if (confs != null && !confs.isEmpty()) {
				ClassLoader cl = ClassUtils.getDefaultClassLoader();
				if (cl != null) {
					Set<Class<?>> rs = new HashSet<Class<?>>(confs.size());
					for (BeanDefinition beanDefinition : confs) {
						if (beanDefinition != null) {
							try {
								rs.add(cl.loadClass(beanDefinition.getBeanClassName()));
							} catch (ClassNotFoundException e) {
								System.out.println("Class.forName error:"+beanDefinition.getBeanClassName());
							}
						}
					}
					return rs;
				}
			}
