解决办法：

     在网上百度一下，说是jdk6以后对于jdk.certpath.disabledAlgorithms 有加强了限制。该配置路径在jre\lib\security\java.security中，改造是将jdk.certpath.disabledAlgorithms 后面的配置删除掉。

    但是对于该jdk配置，本人因能力有限，不敢这么来。

    而是否又会有很么影响，还在探索中。。。。

# Algorithm restrictions for certification path (CertPath) processing
#
# In some environments, certain algorithms or key lengths may be undesirable
# for certification path building and validation. For example, "MD2" is
# generally no longer considered to be a secure hash algorithm. This section
# describes the mechanism for disabling algorithms based on algorithm name
# and/or key length. This includes algorithms used in certificates, as well
# as revocation information such as CRLs and signed OCSP Responses.
#
# The syntax of the disabled algorithm string is described as this Java
# BNF-style:
# DisabledAlgorithms:
# " DisabledAlgorithm { , DisabledAlgorithm } "
#
# DisabledAlgorithm:
# AlgorithmName [Constraint]
#
# AlgorithmName:
# (see below)
#
# Constraint:
# KeySizeConstraint
#
# KeySizeConstraint:
# keySize Operator DecimalInteger
#
# Operator:
# <= | < | == | != | >= | >
#
# DecimalInteger:
# DecimalDigits
#
# DecimalDigits:
# DecimalDigit {DecimalDigit}
#
# DecimalDigit: one of
# 1 2 3 4 5 6 7 8 9 0
#
# The "AlgorithmName" is the standard algorithm name of the disabled
# algorithm. See "Java Cryptography Architecture Standard Algorithm Name
# Documentation" for information about Standard Algorithm Names. Matching
# is performed using a case-insensitive sub-element matching rule. (For
# example, in "SHA1withECDSA" the sub-elements are "SHA1" for hashing and
# "ECDSA" for signatures.) If the assertion "AlgorithmName" is a
# sub-element of the certificate algorithm name, the algorithm will be
# rejected during certification path building and validation. For example,
# the assertion algorithm name "DSA" will disable all certificate algorithms
# that rely on DSA, such as NONEwithDSA, SHA1withDSA. However, the assertion
# will not disable algorithms related to "ECDSA".
#
# A "Constraint" provides further guidance for the algorithm being specified.
# The "KeySizeConstraint" requires a key of a valid size range if the
# "AlgorithmName" is of a key algorithm. The "DecimalInteger" indicates the
# key size specified in number of bits. For example, "RSA keySize <= 1024"
# indicates that any RSA key with key size less than or equal to 1024 bits
# should be disabled, and "RSA keySize < 1024, RSA keySize > 2048" indicates
# that any RSA key with key size less than 1024 or greater than 2048 should
# be disabled. Note that the "KeySizeConstraint" only makes sense to key
# algorithms.
#
# Note: This property is currently used by Oracle's PKIX implementation. It
# is not guaranteed to be examined and used by other implementations.
#
# Example:
# jdk.certpath.disabledAlgorithms=MD2, DSA, RSA keySize < 2048
#
#
jdk.certpath.disabledAlgorithms=
