spring boot configuration file encryption, plaintext password encryption, properties and yml conversion

Keywords: Java Spring Spring Boot

1. Introduce maven


2. Add configuration (yml format; properties and yml online conversion)

properties and yml online conversion: properties and yml online conversion

    algorithm: PBEWithMD5AndDES		#Algorithm - Fixed writing method is generally not changed
    password: 1234qwer				#secret key
    iv-generator-classname: org.jasypt.iv.NoIvGenerator	#Sets the class name of the initial vector IV generator

3. Find the maven warehouse: org\jasypt\jasypt .9.3 and encrypt the content

  1. After opening to the place - enter cmd in the address bar - open the black window

  2. Enter after the window opens

    java -cp jasypt-1.9.3.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="root" password=1234qwer algorithm=PBEWithMD5AndDES

    The java -cp jasypt - version should be modified according to its own. jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input = "plaintext" password = key algorithm = algorithm. These three values should be the same as those in the configuration file

  3. Enter after input
    ----OUTPUT --------------------------- the following is the content after root plaintext encryption

  4. Copy the content (select the encrypted content with the mouse and right-click to copy) - replace the content in the configuration file - replace the password root in the configuration with the newly encrypted content and wrap it with ENC(); Enc () can be changed - if you don't want to use it, you can go to Baidu to change it

4. Common problems and troubleshooting methods

  1. Question 1
    Failed to bind properties under 'spring.datasource.password' to java.lang.String:      
    			Reason: org.jasypt.encryption.pbe.config.SimpleStringPBEConfig.setIvGeneratorClassName(Ljava/lang/String;)V
  2. Question 2
    Failed to bind properties under 'spring.datasource.password' to java.lang.String:
    			Reason: Failed to bind properties under 'spring.datasource.password' to java.lang.String
    			Update your application's configuration
  3. Question 3
    		An attempt was made to call the method org.jasypt.encryption.pbe.config.SimpleStringPBEConfig.setIvGeneratorClassName(Ljava/lang/String;)V but it does not exist. Its class, org.jasypt.encryption.pbe.config.SimpleStringPBEConfig, is available from the following locations:
    		It was loaded from the following location:
    		Correct the classpath of your application so that it contains a single, compatible version of org.jasypt.encryption.pbe.config.SimpleStringPBEConfig
  4. Troubleshooting method
    1. First check whether there are problems in the configuration file and whether there are redundant spaces
    2. Is the version of jasypt-spring-boot-starter.jar too high
    3. No matter what version jasypt-spring-boot-starter.jar is, you can add IV generator classname: org.jasypt.iv.noivgenerator configuration - not only those above 3.0
    4. If all of the above are OK, that is the reason for the jar package conflict (problem 3 is the reason for the jar package conflict)
      View conflicting versions:

1. Click Show dependencies in maven to pop up the left view

2. Search for the jar package used for encryption in the view - in question 3, the jasypt.jar package conflict is reported, so search jasypt directly

3. You can see that two jasypts were found below; Click one of them to locate next to the jasypt package. You have to look for it to find the jasypt package. You can see that there is a conflict between 1.9.3 and 1.9.2 below (then we can look for 1.9.3 and 1.9.2. If you can find it, replace this version with the same one as the other)
