考虑在配置中定义'com.example.transaction.manager.properties.TransacationManagerProperties‘类型的bean

package com.example.transaction.manager.properties;

public class TransactionManagerProperties {
    private String isolationLevel;
    private String propagationBehavior;

    // getters and setters
}

package com.example.transaction.manager.config;

import com.example.transaction.manager.properties.TransactionManagerProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class TransactionManagerConfig {

    @Bean
    public TransactionManagerProperties transactionManagerProperties() {
        TransactionManagerProperties properties = new TransactionManagerProperties();
        properties.setIsolationLevel("READ_COMMITTED");
        properties.setPropagationBehavior("REQUIRED");
        return properties;
    }
}

package com.example.transaction.manager.service;

import com.example.transaction.manager.properties.TransactionManagerProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class TransactionService {

    private final TransactionManagerProperties properties;

    @Autowired
    public TransactionService(TransactionManagerProperties properties) {
        this.properties = properties;
    }

    // service methods
}
